Why the need to use different minimal media to grow bacteria?

I am trying to identify bacteria on skin that can utilise lactic acid as carbon source. So i intend to swab skin and then grow bacteria on minimal media supplemented with lactic acid. My question...

What other phohpshorylated components can i look for downstream of activated FAK and P38 MAPK?

I applied some mechanical stresses on cells and discovered that FAK and p38 MAPK are activated by phosphorylation. For the purpose of publishing, i feel that it will be great if i can look for...

Hypoxia induced: No HIF-1a overexpression seen at transcript level but seen a lot of hypoxia and HIF-1A -induced genes?

hi i need advise on the matter i performed RNA-seq after exposing cells to mechanical stress. I had designed a device to deliver this stress to cells. Looking at the RNA-seq data, i see some...

Proliferation assay : manual cell counting?

How is proliferation assessed by manual cell counting? I will be happy if anyone can provide protocol on this. I have been told this method is much useful than indirect assays like CFSE but i...

QPCR: analyses involving in-between plates?

hi i am not sure if it is alright to analyse my data this way. So i prepared 3 samples of controls, 3 samples of condition at 1hr exposure, 3 samples of condition at 6hr of exposure. i collected...

Time course gene expression analyses: RNA seq over mass spec?

why when wanting to look at genes that respond at say 1hr (early response), 6hr(intermediate response), 16hr (late response) it is better to look at RNA expression rather than protein? has it got...

Why is RNA expression analysis better than protein for looking time course gene expression analysis?

why is it that people usually look at mrna expression rather than protein expression when conducting a time course gene expression analysis?

RNA expression vs protein expression patterns upon stimulation- are RNAs more dynamic?

Let say if i stimulate a cell at 1 hr and 6hr, the RNA expression upregulated at 1 hr may not be reflected at 6hr, but same protein upregulated at 1 hr will be reflected at 6hr. How do i explain...

Phosphoproteome SILAC: can it identify if cells are definitely undergoing apoptosis?

i intend to apply mechanical pressure on cell to look at mechanotransduction pathways. i will be using a SILAC based phosphoproteomics. Can the data also indicate that the cell is undergoing...

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.
