Recombinant Human ICOSLG Protein (Asp19-Ser258), C-hFc and Avi-tagged, Biotinylated
Product Description
Cat
IMP-10422
Official Symbol
ICOSLG
Product Overview
Biotinylated recombinant human B7-H2 protein (Asp19-Ser258) with a Human IgG1 (Pro100-Lys330) Fc tag and Avi-tag at C-terminus was expressed in Chinese Hamster Ovary cell line.
Description
Enables identical protein binding activity. Predicted to be involved in T cell receptor signaling pathway and positive regulation of interleukin-4 production. Located in cytoplasmic ribonucleoprotein granule and plasma membrane.
Expression System
CHO
Species
Human
Tag
C-hFc and Avi
Predicted N Terminal
Asp19
Form
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Conjugate
Biotinylated
Molecular Mass
Predicted Molecular Mass: 55 kDa
SDS-PAGE: 80-100 kDa, under reducing conditions
Protein length
Asp19-Ser258
Bio-activity
The biotin to protein ratio is 0.7 as determined by the HABA assay. Measured by its binding ability in a functional ELISA. When Recombinant Human ICOS Fc Chimera Protein is immobilized at 0.5 μg/mL (100 μL/well), Biotinylated Recombinant Human B7-H2 Fc Chimera Avi-tag that produces a 50% optimal binding response is found to be 1-6 ng/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
Disulfide-linked homodimer, 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
