Gel electrophoresis is the technique where DNA molecules move through the, agarose gel-based on their different mass to charge ratio.
So we made a troubleshooting guide only for you!!

Is SARS-COV-2 biased?

Wondering why some countries are more intensely hit by COVID-19 and some not? Could it be different strategies adopted by their government, quarantine, different genetic population herd immunity? Or could the answer lie within the virus itself?

Do you know how vaccines are made?

Researchers first identify the surface molecules like proteins or sugars which are used by the viruses to first contact the human cells. These molecules are then analyzed for if they can be used to produce an immune response. This is not possible unless the genetic sequence of the virus must be known.

Know your pathogens!

We are surrounded by microbes or microorganisms but not all of them are harmful. Actually some are beneficial for us and harmful microbes are called pathogens. Let Genaxxon help you know them better!
Sanger sequencing technology was the first generation of sequencing and helped provide basic knowledge about genome sequencing but didn’t have the potential for its further improvement. Hence a new technological jump in sequencing expertise was required. That’s when Next Generation Sequencing techniques came into existence and revolutionized our entire capability of genome sequencing.
Extraction and isolation of viral RNA is the first step in the detection and testing of viral RNA by real-time RT-PCR. Here we compare different methods and protocols for extraction of viral RNA.
Nested RT-PCR and real-time RT-PCR are the most common methods for the analysis of viral infections (see Robert Koch Institute >). In contrast to examinations with ELISA or IFA, this can be done at an earlier stage of infection.

A special regulatory strategy of genome translation in RNA viruses and bacterias is mediated via RNA thermometers. RNA thermometers (RNATs) are secondary structures in RNA sequences that are essential for the virulence of the organism. However the base pairing in the RNA thermometers can be altered due to various factors like the thermal denaturation.

Coronavirus motto- Keep mutating!

With the virus already claiming the lives of 1,873 people and infecting 73,333 people around the globe, there is an urgent need to have a strong grip on the virus. Scientists overall are publishing new information in this regard almost every day, one of which is that 2019-nCoV uses the same ACE2 protein to enter the host cells as SARS coronavirus did.

Map the Epitopes like a boss!

With humankind facing a new virus outbreak every now and then, everyone is in the race to develop therapeutics. Out of all the available methods to do so involves knowing the interacting proteins of the pathogen and hosts. The method that uses this approach is known as Epitope Mapping and involves two general strategies.

Decoding the Wuhan coronavirus

The outbreak of a novel coronavirus in Wuhan, China was first reported on 31 December 2019. Just one month later, the World Health Organization has declared the virus a Public Health Emergency of International Concern.
MicroRNAs play a pivotal role in shaping cell phenotype. However, until recently, there were no effective methods to observe miRNA expression within an individual cell, within complex animal tissues, without introducing technical and/or biological artefacts.

The human body is colonized by microorganisms of diverse phylogenetic origins, principally bacteria, archaea, eukaryote, and viruses. In health, specific microbes exist in a symbiotic relationship with their human host, where they contribute essential vitamins and nutrients, prime the human immune system to recognize “non-self” antigens, and produce useful anti-inflammatory compounds that deter disease-causing microbes.

Non-protein-coding RNAs (ncRNAs) are expressed in viruses, archaea, prokaryotes and eukaryotes. They fulfil vital roles in the regulation of chromatin architecture, epigenetic memory, transcription, RNA splicing, editing and turnover. To date, at least 18 distinct types of ncRNA have been identified, which are classified according to their size, function, subcellular localization and target specificity.
Here, we focus on two approaches to the safe and efficient design and delivery of CRISPR/Cas9 gene editing technology.
The development of novel antibacterial drugs, such as synthetic venom antimicrobial peptides (AMPs), is a positive step towards overcoming antimicrobial drug resistance.
To date, several different CRISPR/Cas systems have been isolated and classified according to their molecular structure, substrate specificity and the conditions that support their optimum activity.

Chinese scientists have succeeded in changing the genetic material of pigs so that they are resistant to the CSF virus. A combination of the CRISPR / Cas9 method and the RNA interference (RNAi) technology was used.
Dog`s and cat`s allergy and exclusion diets are often contaminated with foreign proteins and fats. Small amounts of a potential allergen (such as protein of a certain species) in feed are often sufficient to trigger allergic reactions.
Cell-penetrating peptides (CPPs), also known as protein transduction domains (PTDs), are typically 5-30 amino acid residues in length. Whether they occur naturally or are synthetic, CPPs are designed to breach cell membranes and deliver bioactive cargo to the intracellular space.
Wine production, while considered an art form, owes an increasing debt to the latest molecular genetic technologies. Not only do these facilitate batch-to-batch consistency, they also enable the generation of novel strains of grape microflora. While the choice of grapes is important, so too is the interplay between extrinsic and intrinsic factors, and the technological decisions made at every step in the process. Together, these determine whether the finished product will be classed as a “vintage wine”, a “quaffing wine”, or “vinegar”.
What are the differences between proteins, peptides and amino acids and and how did these molecules originally come about?

Proteins - Peptides - Amino acids: What is a Peptide?

miRNAs in Gene Expression

miRNAs occur naturally in animal and plant organisms. They are highly conserved and play an important role in gene regulation, especially in gene silencing. They have an important function in cell differentiation and dedifferentiation, for example in female fertility and preimplantation development.

Digital PCR (dPCR)

Doing digital PCR means to carry out a PCR reaction with only one single amplification step nonetheless resulting in absolute/quantitative values. For dPCR, in contrast to conventional real-time PCR (qPCR), no standard curves, calculating of Ct-values or standard references are required because the single amplification step is performed to obtain a pure yes (positive) or no (negative) answer.
By using the new HotScriptase 2X Cell master mix from Genaxxon RNA viruses (e.g. Zika virus, dengue virus, yellow fever virus) can be detected directly from body fluids as blood, salvia or semen without isolating or purifying RNA prior to RT-PCR.

SNP - Allele Specific Discrimination

There's no accounting for taste.
Cilantro (Coriander): some people love it in their food, some hate it. Here we are detecting a genomic SNP (rs72921001) in HeLa genomic DNA. This SNP is reported to be close to a number of genes coding for olfactory receptors. (Reference: Eriksson N. et al. (2012), "A genetic variant near olfactory receptor genes influences cilantro preference.")

Considering, that only the C-allele specific primer is extended and yielding in a specific amplicon, we can conclude a genetic predisposition in disliking cilantro, as this SNP is significantly associated with detecting a soapy taste to cilantro.

CRISPR/Cas9 optimized workflow

The gRNA ("guide RNA") of the CRISPR/Cas9 system is a short synthetic RNA composed of a sequence (tracrRNA = non-target specific sequence) necessary to bind to the Cas9 protein and a gene specific ca. 20 nucleotide “spacer” or “targeting” sequence (crRNA) which defines the genomic target to be modified. We show in a scheme (according to Liang et al., 2015) an optimized workflow for cell analyzes with the CRISPR/Cas9 system from the theoretical design of the gRNA via transcription and transfection to the analysis of the experimentally obtained data within shortest time with special tips for products to use.

CRISPR/Cas9 Methods

Clustered regularly interspaced short palindromic repeats (CRISPRs) and CRISPR-associated (Cas) systems are revolutionizing the field of genome editing providing a powerful tool for disrupting the gene of interest. Able to achieve highly flexible and specific targeting, CRISPR-Cas systems can be modified and redirected being a powerful tool for genome editing in many species, including mammalian cells.

Our new
HotScriptase RT Cell Mastermix:
For the cDNA synthesis directly from cells, there is no need for a time-consuming and expensive cell lysis or RNA purification any more.
Every single pipetting step and each tube that has to be opened increases the risk of contamination. So far, reverse transcription involved the risk of contaminating the valuable sample by many pipetting steps. With our new all-in-one enzyme > HotScriptase RT Polymerase the risk of contamination is clearly minimized with the zero-step protocol. Moreover, not to mention the considerable time saving.
