What causes conventional PCR product for GAPDH to be shorter than expected?

I design primer pair for house keeping gene mouse Gapdh. According to my calculation, genomic DNA template should produce 600 bp fragment while cDNA template should produce around 400 bp. I...

Why I get band in my PCR negative control?

Lately I am having trouble with PCR genotyping. I keep on getting non specific amplification that have the same size with my target (400 bp). So, I know it's not primer dimer. At first I thought...

Can we mix digestion buffers from different manufacturers in double digestion reaction?

I need to digest my plasmid using BamHI and SacI. Unfortunately, the enzymes came from different manufacturer, Fermentas and Wako Nippongene respectively. I checked the buffer ingredients and they...

Why is my PCR band size less than expected?

My primer set was designed to yield 750 bp fragment. But, on the gel after PCR, I saw clear single band on 500 bp with very faint band around 750 bp. I purified the 500 bp fragment and did direct...

How the parameters (such as Mw, Chemical bonds, polymer bland and so on) affect the mechanic property of polymer (such as storage, loss modulus) ?

Anyone can recommend any books on such topics? Thanks in advance.

Walther Zavala

I am currently doing mouse carcinogenesis experiments in tongue using 4-NQO, diluted in drinking water too.I take tongue tissues after the visual examination show a tumor. In some case the time was more than 16 weeks.

Masita Mandasari

Thank you WZ. Well, it seems that the longer and the higher concentration of the 4NQO treatment, the more severe the cancer will be. Best of luck to all of us.
