Does company brand of cytokines affect differentiation and/or (M0/M1/M2a) polarization of TH1-P cell line into macrophages?

Concerned that there will be functional differences between products from Peprotech vs. Mitenyi vs. R&D.

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)

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.

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?
