What surface receptors in T cells are affected by exogenous ATP?

For flow cytometry purposes, I am interested in treating activated, human PBMCs with a CD39 inhbitor in the presence of several concentrations of exogenous ATP and then measure changes in surface...

Do Hek293 cells naturally express CXCR7?

I've peered through the literature and everything I've read is transfection of CXCR7 into Hek293 cells. So I'm assuming hek293 cells don't. Any tips would be appreciated. Thank you Jordan

I'm growing Hek293 cells, and they are loosely attached to the container they are in. What could be the problem?

My Hek293 cells are grown in MEM media +10% FBS + 2mM glutamine. When the container the cells are in is moved, a clusty of cells would collapse upon itself. I know its not the quality of the FBS,...

Do you know if Cos-7 (monkey kidney fibroblasts) cells express the Gs alpha-subunit?

I need to know if Cos-7 cells naturally express Gs alpha-subunit as I've read several papers that have transfected it into these cell types Any help would be greatly appreciated. Jordan

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...

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....

Is CD44 degraded in lysosome together with hyaluronan after CD44 mediated endocytosis of hyaluronic acid?

Also when RHAMM binds hyaluronic acid, they get internalized, will RHAMM also be degraded? Or both CD44 and RHAMM will be transferred back to the cell membrane? Asking for breast cancer cell line...

Do you need the CMV enhancer before the CMV promotor for a proper function of CMV on the gene that follows?

I'm a student and I have to produce a cell line with a knockin for the NRF2 gene with GFP. I have to put a promotor in front of the GFP because the gene will be too far away from the promotor of...
