ELISA 101 Part 2: ELISA Standards

ELISA (Enzyme Linked Immuno-Sorbent Assay) is a highly sensitive plate-based assay for in vitro quantification of soluble analytes in liquid samples. ELISA can be used to detect and/or quantify any analyte that can be bound by an antibody, such as cytokines, CD antigens, apoptosis markers, hormones, metabolites, growth factors, and more.

Size Selection for NGS

In previous posts about next generation sequencing (NGS), we covered the key steps in library preparation (for RNA-seq), top tips for NGS success, and the ins and outs of long-read DNA sequencing. This time we will look more closely at size selection.

Mycoplasma – The Silent Enemy

Although mycoplasma is the smallest known prokaryotic organism with a tiny size range of 0.15 to 0.35 µm, it can quickly become a huge problem in cell culture labs!

One-Step RT-PCR

Anyone working with gene expression, transcriptional regulation or cDNA cloning will undoubtedly have used reverse-transcription PCR (RT-PCR) at some point in their workflow.

RT-PCR is usually carried out as a two-step process: first, total or mRNA-enriched RNA is converted to complementary DNA (cDNA) by a reverse transcriptase (RT) enzyme. The cDNA is then used as a template for PCR.

Gene Expression Analysis: RNA-Seq or Real-Time PCR?

If you’ve been following our blog posts over the last few months, you’ll have noticed our series on RNA-seq and real-time PCR. Although the underlying principles behind these two techniques are different, both can provide information about the amount (absolute or relative) of mRNA isolated from any sample type.

World Microbiome Day 2020

Today is the 2nd World Microbiome Day, following on from the very first World Microbiome Day, launched by APC Microbiome, at University College Cork in Ireland last year!
