soluble CD40 Ligand, TNFSF5, TRAP, CD154, Gp39, T-BAM, sCD40 Ligand
Measure by its ability to induce IL-8 secretion in human PBMCs.
The ED50 for this effect is <5 ng/mL.
CD40, belonging to the TNF receptor family, is a cell surface protein generally expressed on B cells, dendritic cells, monocytes, thymic epithelial cells and on T cells at low levels. The membrane-anchored CD40 Ligand is expressed almost exclusively on activated CD4+ T lymphocytes. CD40 signaling plays a significant role immunoglobulin (Ig) class switching, and is critical for the proliferation and differentiation of B cells. A disease "immunodeficiency with hyper-IgM", characterized by failure to produce IgG, IgA and IgE due to failure expression of CD40L. The soluble form of CD40L is produced in vivo by an intracellular proteolytic processing of the entire TNF homologous region (18 kDa protein) of CD40L.

The protein was lyophilized from a solution containing 1X PBS, pH 8.0.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Blue Ice
Lyophilized protein should be stored at -20°C for 1 year.
Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1%
BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months.

Note: Application as IHC, only suitable for histochemical staining or fluorescence staining of paraffin-embedded sections. Application as ICC/IF, suitable for histochemical or fluorescent staining of frozen sections, as well as chemical and fluorescent staining at the cellular level.
注意:抗体应用为IHC的,抗体只适合于石蜡切片的组化染色或者荧光染色。
抗体应用为IF/ICC的,抗体适合于冰冻切片的组化染色或者荧光染色,以及细胞水平的化学染色和荧光染色。
