Cat

IMP-648

Official Symbol

FCGR3B

Product Overview

Biotinylated Recombinant Human FCGR3B protein(Accession # O75015)(Gly 17-Ser 200), fused to C-His-Avi Tag, was expressed in HEK293.

Expression System

HEK293

Species

Human

Tag

C-His-Avi Tag, Biotinylated

Form

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Molecular Mass

The protein has a calculated MW of 24.6 kDa. The protein migrates as 38-48 KDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Gly 17-Ser 200

Endotoxin

Less than 1.0 EU per μg 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 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
