Recombinant Human sCD40L Protein (Fc Tag)

Product Specifications

Background

The protein encoded by this gene is expressed on the surface of T cells. It regulates B cell function by engaging CD40 on the B cell surface. A defect in this gene results in an inability to undergo immunoglobulin class switch and is associated with an hyper-IgM syndrome.

Abbreviation

SCD40L
