Is it possible that cell line (OSCC) will grow symbiotically with bacteria?

I observed some moving particles "'not sure if bacteria" in some OSCC cells in culture,. The cells are growing well despite on those moving materials.

Any idea how to troubleshoot my problem with target stable cell lines.?

Good day!I am currently generating stable cell lines( KON ) using TTA vector and G418 as drug selection agent.?After two weeks i got isolated colony from some wells at the 900ug/ml (G418). I...

Good day! I am doing drug screening for Oral squamous Carcinoma cell Lines. My drug G418 concentration is from 100 ug to 100ug per ml?

It turns out that my cells become 100 percent (from 70% confluent) confluent the after 4 days? Any suggestion On optimizing drug screening.?

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...

What could be some reasons why unstimulated monocytes are getting activated?

Im doing PBMC isolation -> CD14+ enrichment using magnetic beads -> stimulation setup. My negative control is just cells in cRPMI but they seem to get activated over and over again.

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...
