How can I find the transfection efficiency when we use commercially available non-fluorescent siRNA for transfection?

I have used commercially control and target siRNA from SantaCruz to perform transfection in C2C12 and HSMM. I performed western blot and the target protein was not expressed while the controls...

Why does blocking with my immunogenic peptide cause nuclear fluorescence in ICC?

Hi all, I am validating a polyclonal antibody raised against human ANT4, through WB and ICC. In most of my controls, the antibody shows very little off-target binding, but when I pre-incubate the...

Has anyone had luck using cell lines other than HEK 293 (such as COS1) to package lentivirus?

I am looking to package lentivirus in endothelial cells but I am opposed to using 293 cells due to personal ethics regarding the source. I have done some reading and saw that COS1, COS7, & CHO...
