About CD45
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitosis, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus is classified as a receptor type PTP. This PTP has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes, or by activating various Src family kinases required for the antigen receptor signaling. This PTP also suppresses JAK kinases, and thus functions as a regulator of cytokine receptor signaling. Alternatively spliced transcripts variants of this gene, which encode distinct isoforms, have been reported. [provided by RefSeq, Jun 2012]

About CF488A
CF®488A from Biotium is a fluorophore with an excitation peak at 490 nm and an emission peak at 515 nm. It is spectrally similar to Fluorescein, Alexa Fluor™ 488 and DyLight™ 488. It can be use in fluorescence microscopy and flow cytometry. In microscopy, CF®488A has been specifically validated for STORM, STED, Structured Illumination (SIM), 2-Photon microscopy and TIRF.
