Product Description

Cat

IMP-617

Official Symbol

TNF

Product Overview

FITC-Labeled Recombinant Human TNF protein(NP_000585.2)(Leu 25-Ser 645), fused to C-His Tag, was expressed in HEK293.

Expression System

HEK293

Species

Human

Tag

C-His Tag, FITC-Labeled

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 70.5 kDa. The protein migrates as 85-105 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Leu 25-Ser 645

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 protect from light and 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.

SDS-PAGE

Bioactivity-ELISA 1

Immobilized Cetuximab at 2 μg/mL (100 μL/well) can bind FITC-Labeled Human EGF R, His Tag with a linear range of 0.039-0.313 μg/mL.

Bioactivity-FACS 1

2e5 of Anti-EGFR CAR-293 cells were stained with 100 μL of 1 μg/mL of FITC-Labeled Human EGF R Protein, His Tag and negative control protein respectively, FITC signal was used to evaluate the binding activity.
