Name : Human BDCA-2 Protein
Product Source :
Recombinant Human BDCA-2 Protein is expressed from HEK293 with His tag at the N-Terminus. It contains Phe46-Ile213.[Accession | Q8WTT0-1]
Molecular Weight :
The protein has a predicted MW of 20.93 kDa. Due to glycosylation, the protein migrates to 30-40 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE
Formulation :
Supplied as 0.22μm filtered solution in 20mM Tris, 500mM NaCl, 200mM L-arginine (pH 8.5).
Reconstitution :
Storage and Stability :
Valid for 12 months from date of receipt when stored at -80°C.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human BDCA-2 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. ELISA Data Immobilized Human BDCA-2, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-BDCA-2 Antibody, hFc Tag with the EC50 of 1.3ng/ml determined by ELISA (QC Test). SPR Data Anti-BDCA-2 Antibody captured on CM5 Chip via Protein A can bind Human BDCA-2, His Tag with an affinity constant of 2.97 nM as determined in SPR assay (Biacore T200) (Routine Test).
Background :
BDCA-2, BDCA-3, and BDCA-4. In blood, BDCA-2 and BDCA-4 are expressed on CD11c(-) CD123(bright) plasmacytoid dendritic cells, whereas BDCA-3 is expressed on small population of CD11c() CD123(-) dendritic cells. All three Ags are not detectable on a third blood dendritic cell population, which is CD1c() CD11c(bright) CD123(dim), or on any other cells in blood.BDCA-2 is completely down-regulated on plasmacytoid CD11c(-) CD123(bright) dendritic cells, BDCA-2 is rapidly internalized at 37 degrees C after mAb labeling.
