. Immobilized recombinant human CD40 at 2 μg/ml (100 μl/well) can bind biotinylated human CD40L with a linear range of 15.6-500 ng/ml.
蛋白构建
A DNA sequence encoding the human CD40 (NP_001241.1) extracellular domain (Met 1-Arg 193) was expressed, with a C-terminal polyhistidine tag.
NP No.

分子量
The secreted recombinant human CD40 comprises 184 amino acids with a predicted molecular mass of 20.7 kDa. As a result of glycosylation, rhCD40 migrates as an approximately 32 kDa band in SDS-PAGE under reducing conditions.
缓冲液
Lyophilized from sterile PBS, pH 7.4
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

CD40 背景信息

CD40, also known as TNFRSF5, is a member of the TNF receptor superfamily which are single transmembrane-spanning glycoproteins. CD40 protein plays an essential role in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. CD40 protein is expressed in B cells, dendritic cells, macrophages, endothelial cells, and several tumor cell lines. Defects in CD40 result in hyper-IgM immunodeficiency type 3 (HIGM3). In addition, CD40/CD40L interaction is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis.
