Can the RNASE H1 and H2A proteins be inhibited?

I am looking for a way to inhibit the catalytic function of RNASE H1 and RNASE H2A on the protein level (so not via shRNAs or something similar). Sadly, I just found inhibitors for other...

Is it possible to co-express a sgRNA (CRISPR/Cas9) and a protein-coding gene?

I want to express a sgRNA for CRISPR/Cas9-based genome editing, which should be expressed at similar levels than a protein-coding gene? Are there any known systems or do you have anything in mind,...

What is the best way to reduce error rates in array synthesized DNA oligonucleotide libraries?

I am looking for ways to reduce the error rates of array synthesised DNA oligonucleotide libraries of, say, approx. 100 000 unique sequences with 170 bps. These have error rates of approx. 0.5%...

How do I insert DNA barcodes into animal cells and how do I transmit them to the neighbouring cells?

I am currently interested in equipping animal cells in a tissue with individual barcodes. These barcodes should get amplified in the cells (not to a cell degrading extent, of course), and also...

Is it possible the cut the ends of DNA fragments to obtain sticky ends?

Assume we are given a DNA fragment like ACTTAGC....GCTCGGCA TGAATCG...CGAGCCGT so we have blunt ends. I am looking for a nuclease, that cleaves the end, such that we obtain sticky ends. Hence, the...
