About CTLA-4
This gene is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.

About CF405M
CF®405M from Biotium is a fluorophore with an excitation peak at 408 nm and an emission peak at 452 nm. It is spectrally similar to Pacific Blue, V450 and DY-415. It can be use in fluorescence microscopy and flow cytometry. Specifically, it has been validated for use in STED, Structured Illumination (SIM) and 2-Photon microscopy. In flow cytometry, superior alternatives are Brilliant™ Violet 480, Brilliant™ Violet 510 and StarBright Violet 515.
