Quantifying Allele-Specific Gene Expression Using PCR-Based Methods

By Colin Shepherd | November 16, 2017

Allele-specific expression can occur for various biological reasons, such as gene imprinting, or differential transcription caused by mutations, or single nucleotide polymorphisms (SNPs), or epigenetic alterations. Traditional end-point RT-PCR or qRT-PCR-based methods only detect overall levels of mRNA expression from a given gene rather than mRNA transcripts originating from individuals. If your project requires more…

iPOND, Part 1: Fishing for Proteins with DNA as Bait

By Camilla S. Colding-Christensen | November 14, 2017

No, iPOND is not a sleek electronic fishing device from Apple. However, if you thought about fishing, well, you’re not far off the mark. If you find yourself wondering which proteins are present at DNA during or after replication, iPOND is an elegant technique to help you find out. In this article, I will explain…
