Gram-negative pathogens, such as Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii are now responsible for many infections, including infections occurring in hospitals. Because of their broad spectrum of antibiotic resistance many antibiotics may now longer work well. A few years after… Read More ›

How does the BNA[NC] bead-based assay for somatic mutations work?
Shivarov et al. designed and validated this BNA[NC] probe bead-based assay for the Luminex Lab Scan 200 flow platform to allow for the detection and quantification of somatic mutations in Leukemia! -.- How does the assay work? Primers are designed… Read More ›
Is Targeted Insertion of Short DNA Fragments into Mammalian Cells Possible?
Recently the Targeted Insertion of Short DNA Fragments into Mammalian Cells was Shown to be Possible with the help of CRISPR Cas! The direct injection of Cas9 mRNA, sgRNAs, and DNA oligos or vectors into mammalian cells was reported as… Read More ›
What are Circular Oligonucleotides?
Circular oligonucleotides are covalently closed singular DNA or RNA strands that are resistant to degradation by many cellular DNA and RNA decay machineries. [Source: (left) Modelling DNA; Phil. Trans. R. Soc. A-2006-Harris-3319-34; (right) David Goodsell: The self-splicing RNA in PDB… Read More ›
Are MicroRNAs the new players in metabolism and metabolic disorders?
Micro RNAs (miRNAs) have recently emerged as key regulators of metabolic processes! . More and more evidence is accumulating that suggest that the dysregulation of miRNAs may contribute to metabolic abnormalities such as the misregulation of cholesterol and lipid metabolism, insulin… Read More ›
Why should I test my CHO cell culture for virus infections?
The answer is: … CHO cells can be infected in bioreactors with viruses such as Vesivirus 2117! … The presence of a virus in a bioreactor can inflict major losses for biotech and pharmaceutical companies involved in the manufacturing of… Read More ›
What are Long or large non-coding RNAs (lncRNAs)?
Long or large non-coding RNAs (lncRNAs) are non-protein coding sequence transcripts ! . Long non-coding RNAs are non-protein coding sequence transcripts that contain more than 200 nucleotides. The size of these RNA molecules distinguishes them from small regulatory RNAs such… Read More ›

What are Micro peptides?
Micro peptides are short, unprocessed peptides with biological functions! . Do noncoding RNAs (ncRNAs) code for micro peptides? . Yes, apparently this appears to be the case! . In protein synthesis RNA acts as a template for cellular proteins and… Read More ›
What are MicroRNAs and what do they do?
MicroRNAs are small non-coding single-stranded RNA molecules MicroRNAs (miRNAs) are small non-coding single-stranded RNA molecules consisting of approximately 21 to 22 nucleotides that regulate posttranscriptional gene expression in metazoans and plants. miRNAs are usually generated from noncoding regions of gene… Read More ›
