Can eQTL be validated by wet-lab experiments?

eQTL = Expression quantitative trait loci (eQTLs) are genomic loci that contribute to variation in expression levels of mRNAs. In other words, a SNP regulating RNA expression level of a gene. Is...

Is there a quick assay that tells the rate of mutation accumulation of a cancer cell line in different time points?

Except using illumina's sequencing. I am looking for a cheap and quick essay that can estimate the rate of mutation accumulation.

What can I do with Cancer Exome-Seq data without matched normal?

Dear scientists, I am aware that tumor exome-seq data without a matched normal will have difficulty for distinguishing somatic and germline mutations. I aim to find "important" somatic mutations...

Is there a method to extract tumours and adjacent normal tissues from mice multiple times?

I am wondering if there is a method for dissecting adjacent normal and tumor samples from living mice without sacrificing the mouse? I hope to study the tumor evolution at multiple time points...

Would RNA quality/quantity be good enough for sequencing when the liver tumor samples are frozen and sliced?

One of my colleague thinks that the RNA quality should be fine for those cryo-sliced liver tumor samples. We just need to use more sliced samples to get enough RNA. Is this correct?

Where do I find the number of common genes between two species?

In trees of life, people have been using the degree of conservation to assign the branches. I am wondering where I can look up for the numbers representing the diversity or commonality between two...

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....
