Invitrogen™ CD100 Recombinant Rabbit Monoclonal Antibody (010), PE

Description

Preparation: This antibody was obtained from a rabbit immunized with purified, recombinant Mouse CD100 (SEMA4D) (Met1-Arg733) and conjugated with PE under optimum conditions, the unreacted PE was removed. Storage: This antibody can be stored at 2C-8C for twelve months without detectable loss of activity. Protected from prolonged exposure to light. Do not freeze! Sodium azide is toxic to cells and should be disposed of properly. Flush with large volumes of water during disposal.

Semaphorins are neuronal chemorepellants that direct pioneering neurons during nervous system development. CD100 (also known as semaphorin 4d), a 150 kDa homodimer, is a novel semaphorin that induces B cells to aggregate and improves their viability in vitro. CD100 modifies CD40-CD40L B cell signaling by augmenting B cell aggregation and survival and down regulating CD23 expression. CD72 is a lymphocyte receptor for the class IV semaphorin CD100, which is involved in regulating B cell signaling. CD100 is expressed on resting and PHA stimulated T cells. The protein is weakly expressed on NK cells, EBV transformed B cells, monocytes and tumor/peripheral blood T cell lines, and at higher density on activated T cells and B cells.
