About MATK
The protein encoded by this gene has amino acid sequence similarity to Csk tyrosine kinase and has the structural features of the CSK subfamily: SRC homology SH2 and SH3 domains, a catalytic domain, a unique N terminus, lack of myristylation signals, lack of a negative regulatory phosphorylation site, and lack of an autophosphorylation site. This protein is thought to play a significant role in the signal transduction of hematopoietic cells. It is able to phosphorylate and inactivate Src family kinases, and may play an inhibitory role in the control of T-cell proliferation. This protein might be involved in signaling in some cases of breast cancer. Three alternatively spliced transcript variants that encode different isoforms have been described for this gene.

About PerCP
Peridinin-Chlorophyll-Protein (PerCP) is a red-emitting fluorescent protein isolated from algae that can be excited by the 488 nm blue laser and captured with a 670/30 nm bandpass filter. PerCP exhibits a large Stokes' Shift, with an excitation peak at 482 nm and an emission peak at 675 nm. PerCP is was historically used in flow cytometry, however it is highly susceptible to photobleaching and has poor stability. Alternatives like BB700, NovaFluor Blue 690 or PerCP-eFluor™ 710 are preferred. PerCP is a generic dye that has no sole manufacturer.
