Product Description

Cat

IMP-620

Official Symbol

VEGFA

Product Overview

Recombinant Human VEGFA protein(NP_001020537.2)(Ala 27-Arg 191) was expressed in HEK293., Biotinylated

Expression System

HEK293

Species

Human

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 19.2 kDa. As a result of glycosylation, the protein migrates as 25-30 kDa (monomer) under reducing (R) condition, and 43-50 kDa under non-reducing (NR) condition (SDS-PAGE).

Protein length

Ala 27-Arg 191

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>95% 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 24 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.

SDS-PAGE
