Regulatory Status Legend
The MIH32 monoclonal antibody specifically binds to CD276, also known as B7-H3 (B7 homolog 3). CD276 is a type I transmembrane glycoprotein and member of the B7-family of regulatory proteins. The expression of B7-H3 can be induced on T cells, natural killer (NK) cells and antigen presenting cells. B7-H3 is up-regulated during the differentiation of monocytes into dendritic cells or during the interaction between dendritic cells and regulatory T cells. In addition, B7-H3 is found to be expressed on fibroblasts, fibroblast-like synoviocytes and epithelial cells. CD276 (B7-H3) can function as a positive or a negative regulator of T responses.
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.
