About CD5
This gene encodes a member of the scavenger receptor cysteine-rich (SRCR) superfamily. Members of this family are secreted or membrane-anchored proteins mainly found in cells associated with the immune system. This protein is a type-I transmembrane glycoprotein found on the surface of thymocytes, T lymphocytes and a subset of B lymphocytes. The encoded protein contains three SRCR domains and may act as a receptor to regulate T-cell proliferation. Alternative splicing results in multiple transcript variants encoding different isoforms.

About CF405S
CF®405S from Biotium is a fluorophore with an excitation peak at 404 nm and an emission peak at 431 nm. It is spectrally similar to Alexa Fluor™ 405. It can be use in fluorescence microscopy, specifically its been validated in Structured Illumination (SIM), and flow cytometry. However, in flow cytometry, superior alternatives are Brilliant™ Violet 421, SuperNova v428 and StarBright Violet 440.
