Product Description

Cat

IMP-204

Official Symbol

CTLA4

Product Overview

Recombinant Rabbit CTLA4 protein(AA Lys 36-Asp 161)(Accession # P42072) is expressed from human 293 cells (HEK293). This protein carries a human IgG1 Fc tag at the C-terminus.

Expression System

HEK293

Species

Rabbit

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 40.3 kDa. The protein migrates as 50-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Lys 36-Asp 161

Endotoxin

Less than 1.0 EU per ug by the LAL method.

Purity

>95% as determined by 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

Rabbit CTLA-4, 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 95%.
