Recombinant Human CD200 Protein (Gln31-Lys232), C-6×His and Avi-tagged, Biotinylated
Product Description
Cat
IMP-10258
Official Symbol
CD200
Product Overview
Biotinylated recombinant human CD200 protein (Gln31-Lys232) with 6×His tag and Avi-tag at C-terminus was expressed in Human embryonic kidney cell.
Description
This gene encodes a type I membrane glycoprotein containing two extracellular immunoglobulin domains, a transmembrane and a cytoplasmic domain. This gene is expressed by various cell types, including B cells, a subset of T cells, thymocytes, endothelial cells, and neurons. The encoded protein plays an important role in immunosuppression and regulation of anti-tumor activity. Alternative splicing results in multiple transcript variants encoding different isoforms.
Expression System
HEK293
Species
Human
Tag
C-6×His and Avi
Predicted N Terminal
Gln31 inferred from enzymatic pyroglutamate treatment revealing Val32.
Form
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Conjugate
Biotinylated
Molecular Mass
Predicted Molecular Mass: 26 kDa
SDS-PAGE: 40-50 kDa, under reducing conditions
Protein length
Gln31-Lys232
Bio-activity
The biotin to protein ratio is greater than 0.7 as determined by the HABA assay. Measured by its binding ability in a functional ELISA. When Recombinant Human CD200R1 Fc Chimera is immobilized at 2 μg/mL (100 μL/well), Biotinylated Recombinant Human CD200 His-tag Avi-tag binds with an ED50 of 0.1-0.6 μg/mL.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Notes
Biotinylated via Avi-tag.
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution
Reconstitute at 500 μg/mL in PBS.
SDS-PAGE
SDS-PAGE
