Any suggestions on how else I can label the nuclei of a cancer cell line that has formed a 3D cellular aggregate?

I used NucBlue Live from ThermoFisher (https://www.thermofisher.com/sg/en/home/references/protocols/cell-and-tissue-analysis/protocols/nucblue-live-readyprobes-protocol.html). I found that this...

Any suggestions on how I can inhibit secretion of cytokines by a cancer cell line without killing the cells?

These 'secretion-inhibited' cancer cells would then be co-cultured together with myeloid cells so I am hoping the environment would not be toxic to both cell types.

Is it neccessary to use filtered pipette tips when adding lysis solution to lyse cells for downstream RNA work?

Or is the use of filtered tips only crucial from the point of isolating RNA from the lysate? (i.e. after obtaining the lysate)

Can anyone share how they label monocytes with CellTracker Orange(CMRA)?

I use IMDM as staining buffer (is this ok?),but lose 60% cells after staining. Also, any idea/comment on why we should avoid amine-containing or thiol-containing buffers as the staining buffer?

What markers can I use to characterize macrophage subsets (M1 and M2)? And what about different monocyte subsets (e.g. patrolling, etc)?

For immunostaining of cells that are fixed.

Arena simulation - how do i model the following model in ARENA (see description) (new to ARENA)?

Hello, I'm fairly new to ARENA and I have the following problem: I have two queues in which, in each queue, a different order type arrives (both having an arrival rate of exponential 10). Order...
