Source

Human TDGF1, Fc Tag (CRO-H5253) is expressed from human 293 cells (HEK293). It contains AA Leu 31 - Thr 172 (Accession # NP_003203).

Predicted N-terminus: Leu 31

Molecular Characterization

TDGF1(Leu 31 - Thr 172)NP_003203
Fc(Pro 100 - Lys 330)P01857

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 42.6 kDa. The protein migrates as 44-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>92% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

Reconstitution

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Please avoid repeated freeze-thaw cycles.

No activity loss is observed after storage at:

  1. 4-8°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

SDS-PAGE

Human TDGF1, Fc Tag (Cat. No. CRO-H5253) SDS-PAGE gel

Human TDGF1, 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 92%.

 

Background

Teratocarcinoma-derived growth factor 1 (TDGF1) is also known as Cripto-1 growth factor (CRGF), Epidermal growth factor-like cripto protein CR1, CRIPTO, is a cell membrane which contains one EGF-like domain. TDGF1 is preferentially expressed in gastric and colorectal carcinomas than in their normal counterparts. TDGF1 interacts with the activin type-1 receptor ACVR1B. TDGF1 could play a role in the determination of the epiblastic cells that subsequently give rise to the mesoderm.
