Does anyone know of an antibody that is specific for the GOLLI region of GOLLI-MBP proteins?

I need to distinguish GOLLI proteins from their related myelin basic protein isoforms. It seems that most GOLLI-MBP antibodies are specific for the MBP containing regions of the proteins and...

How can I delete a short (42bp) section of a plasmid (~9kb) and replace it with another (57bp) fragment without using restriction sites?

There are a lot of techniques that may accomplish this, such as overlap extension PCR and adaptions of Gibson, CPEC, etc. My experience with these is limited, however, and I would appreciate any...

Has anyone ever experienced warping/melting of gels in a biorad mini-protean gel box?

I am running hand cast 12% bis-tris gels using MES buffer (novex formulations) at 100v. Every so often, towards the end of the run I notice a warping of the gel at the bottom corners which...

Is it necessary to increase the annealing temperature after a few rounds of PCR when introducing restriction sites?

I'm designing specific primers to clone a small (~298 bp) fragment from a plasmid and introduce restriction sites. Both forward and reverse complement primers are 27 bp, no hairpins, non-self...

What is the best procedure for getting RNA from small numbers of cells (<100,000)?

We are doing a cell sorting experiment and many of the fractions I would like to analyze are yielding between 50,000 - 100,000 cells. I am looking for a good procedure for high RNA yields that...

Is there a good method for isolating mRNAs from p bodies? Can I simply use an Ago 2 pulldown and then isolate the mRNA from that?

I would like to know if my particular mRNA is being transitioned in and out of p bodies under certain conditions. Looking by qPCR I can see clear changes in transcript levels, but I never see...

For qPCR, what should be used as the comparator?

I need to settle a disagreement with a colleague about how best to present some qPCR data. We have two mice strains (a wild-type and a transgenic), both were treated with a drug and with saline...

How to do error propogation in qPCR (ddCt method)?

I have read many many papers on this and every day I come up with a different answer! My experiments usually consist of multiple transgenic animal lines including WT, treated with either saline...

What is the best way to block miRNA?

miRNA seems to be at the center of translational regulation for many proteins. To study this phenomena there are many commercially available miRNA inhibitors as well as miRNA mimics. After...
