Recombinant Mouse TROP-2 / TACSTD2 Protein, His Tag, 200 µg

Background
TROP-2 is a single-copy gene in human cells, and encodes a type-1 transmembrane glycoprotein which is over-expressed in various malignancies, also referred to as tumor associated calcium signal transducer 2 (TACSTD2), GA733-1 or M1S1. TROP-2 is related to epithelial cell adhesion molecule (EpCAM), also called TROP-1, gp40, and KSA. Trop-1 and Trop-2 are homologous to serum IGF-II-binding proteins and appear as signal transducers. Thus, they likely represent novel cell-surface receptors and may play a role in regulating the growth of carcinoma cells.

Source
Recombinant Mouse TROP-2, His Tag (TR2-M52H6) is expressed from human 293 cells (HEK293). It contains AA Gln 25 - Gly 270 (Accession # Q8BGV3-1).
Predicted N-terminus: Gln 25

Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 29.9 kDa. The protein migrates as 38-48 kDa under reducing (R) condition (SDS-PAGE) due to Glycosylation.

Endotoxin
Less than 1.0 EU per μg by the LAL method.

Purity
>90% as determined by SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Trehalose are added as protectants before lyophilization.

Reconstitution
See Certificate of Analysis for reconstitution instructions and specific concentrations.

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.

Bioactivity
Please refer to product data sheet.
