Recombinant Human EPCAM Protein (Gln24-Lys265), C-hFc and Avi-tagged, Biotinylated
Product Description
Cat
IMP-10086
Official Symbol
EPCAM
Product Overview
Biotinylated recombinant human EpCAM/TROP1 protein (Gln24-Lys265) with a Human IgG1 (Pro100-Lys330) Fc tag and Avi-tag at C-terminus was expressed in Human embryonic kidney cell.
Description
This gene encodes a carcinoma-associated antigen and is a member of a family that includes at least two type I membrane proteins. This antigen is expressed on most normal epithelial cells and gastrointestinal carcinomas and functions as a homotypic calcium-independent cell adhesion molecule. The antigen is being used as a target for immunotherapy treatment of human carcinomas. Mutations in this gene result in congenital tufting enteropathy.
Expression System
HEK293
Species
Human
Tag
C-hFc and Avi
Predicted N Terminal
Gln24, inferred from deblocking reaction revealing Glu25.
Form
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Conjugate
Biotinylated
Molecular Mass
Predicted Molecular Mass: 56 kDa
SDS-PAGE: 55-75 kDa, under reducing conditions
Protein length
Gln24-Lys265
Bio-activity
Measured by its binding ability in a functional ELISA. When Human EpCAM/TROP1 Affinity Purified Polyclonal Antibody is immobilized at 0.25 μg/mL (100 μL/well), it binds to Biotinylated Recombinant Human EpCAM/TROP-1 Fc Chimera Avi-tag with an ED50 of 1-6 ng/mL. Measured by the ability of the immobilized protein to support the adhesion of the L Cells mouse fibroblast cell line. The ED50 for this effect is 0.7-2.8 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
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
