Human CD40 Ligand (hCD40L) Recombinant Protein #32621

    Product Information

    Product Usage Information

    Working concentration of recombinant hCD40L generally ranges from 1-100 ng/ml.

    Storage

    Recombinant human CD40L is supplied as lyophilized material that is very stable at -20°C. It is recommended to reconstitute with sterile water at a concentration of 0.1 mg/ml, which can be further diluted in aqueous solutions as needed. Addition of a carrier protein (0.1% HSA or BSA) is recommended for long term storage.

    Once in solution, store at 4°C and use within 1 month, or store at -20ºC to -80ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles if storing reconstituted material at -20ºC to -80ºC.

    Product Description

    MW (kDa) 16
    Purity A greater than 95% purity was determined by SDS-PAGE.
    Endotoxin Less than or equal to 1 EU / 1 μg hCD40L.
    Activity The bioactivity of recombinant hCD40L was determined by measuring the secreted embryonic alkaline phosphatase (SEAP) activity in HEK-blue™ CD40L responsive indicator cells. The ED50 of each lot is between 5-50 ng/ml.

    Source / Purification

    Recombinant human CD40L was expressed in E. coli and is supplied in a lyophilized form.

    Background

    CD40 Ligand (CD40L), a member of the TNF superfamily of ligands, is expressed as either a membrane-bound or soluble homotrimer (1). Both membrane-bound and soluble forms of CD40L have biological activity (1,2). CD40L is expressed primarily on activated T cells; however, mast cells, basophils, and NK cells may also express CD40L (1). CD40L functions as an important T cell co-stimulatory molecule and enhances T-dependent B cell responses (1,2). CD40L binds CD40, which is a receptor expressed on B cells, dendritic cells, and macrophages (1). Binding of CD40L to CD40 leads to the recruitment of TRAF proteins (TRAFs 2,3,5, and 6) resulting in the activation of the JNK and NF-κB pathways (1,2).
