CD21 Protein, Mouse, Recombinant (His)

A natural soluble form of CD21 that is cleaved from lymphocyte membrane CD21 circulates in normal human serum. Soluble CD21 retains the capacity to bind iC3b and CD23, the known ligands of membrane CD21. In a similar fashion to IgE complexes, another ligand of CD23, the soluble CD21 was shown to efficiently trigger CD23-signalling pathways in human monocytes.

Description

Species	Mouse
Expression System	HEK293
Tag	C-His
Accession Number	P19070
Synonyms	C3DRSLEB9, CR2, CVID7, C3DR, CD21, SLEB9, EBV receptor
Construction	Recombinant Mouse CD21 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ile12-Trp963.[Accession \|P19070]
Protein Purity	> 90% as determined by Tris-Bis PAGE
Molecular Weight	The protein has a predicted MW of 106.03 kDa. Due to glycosylation, the protein migrates to 130-160 kDa based on Tris-Bis PAGE result.

Endotoxin	Less than 1EU per μg by the LAL method.
Formulation	Supplied as 0.22μm filtered solution in PBS (pH 7.4).
Stability & Storage	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.
Shipping	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.
