Regulatory Status Legend
The Q38-480 monoclonal antibody specifically binds to mouse CD150, also known as SLAM (signaling lymphocyte activation molecule). CD150 is a type 1 transmembrane glycoprotein that is a member of the CD2 subfamily of the Ig superfamily. It is encoded by the Slamf1 (signaling lymphocytic activation molecule family member 1) gene. CD150 is differentially expressed on subsets of thymocytes, T and B lymphocytes, dendritic cells, macrophages, and endothelial cells. SLAM plays multiple roles in innate and adaptive immunity serving as an adhesion molecule and/or coreceptor. CD150-mediated costimulation of TCR-activated T cells reportedly results in the increased production of IFN-γ by Th1 cells and is required for IL-4 production by T follicular helper cells. CD150 also plays important roles in hematopoietic cell developmental pathways. CD150 is differentially expressed by self-renewing adult hematopoietic stem cells (HSC) whereas non-multipotent hematopoietic progenitor cells are CD150-. Utilizing additional cell surface markers, lineage-negative CD150+CD48-CD41- cell fractions are reported to be highly enriched for adult HSC.
Alexa Fluor® 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor® 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
