Product Description

Cat

IMP-114

Official Symbol

HHLA2

Product Overview

Recombinant Human HHLA2 protein(AA Ile 23-Asn 344)(Accession # Q9UM44-1) is expressed from human 293 cells (HEK293). This protein carries a human IgG1 Fc tag at the C-terminus.

Expression System

HEK293

Species

Human

Tag

C-Fc Tag

Form

Lyophilized from sterile Tris with Glycine, Arginine and NaCl, pH7.5, 10% trehalose.

Molecular Mass

This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 63.4 kDa. The protein migrates as 80-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Ile 23-Asn 344

Endotoxin

Less than 1.0 EU per ug by the LAL method.

Purity

>90% as determined by reduced SDS-PAGE.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.

SDS-PAGE

Human B7-H7, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

Bioactivity-ELISA 1

Immobilized Human CD28H, His Tag at 5 ug/mL (100 uL/well) can bind Human B7-H7, Fc Tag with a linear range of 1-78 ng/mL.
