Recombinant Human IL21R protein, C-His Tag

Product Description

Cat

IMP-2977

Official Symbol

IL21R

Product Overview

Recombinant Human IL21R protein(20-232aa), fused with C-terminal His Tag, was expressed in HEK293.

Expression System

HEK293

Species

Human

Tag

C-His Tag

Form

Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8% trehalose is added as protectants before lyophilization.

Molecular Mass

The protein has a predicted molecular mass of 25.4 kDa after removal of the signal peptide.The apparent molecular mass of IL21R-His is approximately 35-55 kDa due to glycosylation.

Protein length

20-232aa

Purity

The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.

Biological Activity

ELISA plate pre-coated by 2 μg/ml (100 μl/well) Human IL21R, His tagged protein can bind Human IL21, hFc Tagged protein in a linear range of 1.6-40 ng/ml.

Storage

Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing).Lyophilized proteins are shipped at ambient temperature.

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
