Product sheet for recombinant human EpCAM protein (TL-668) detailing expression host, purity, molecular weight, storage and activity.
This one‑page product sheet describes the recombinant human EpCAM protein (TL-668) produced in human HEK293 cells. It lists the protein’s synonyms, sequence, predicted molecular weight (29.1 kDa), purity (≥95 %), endotoxin level (<0.1 EU/µg) and the purification method (chromatography).\n\nThe sheet also provides formulation details (6 % mannitol in sterile PBS, pH 7.4 lyophilized powder), storage conditions (4 °C for 24 months, reconstituted solution at –20 °C for 6‑12 months) and a brief mechanism of action, noting EpCAM’s role in epithelial cell adhesion and its relevance as a tumor marker. References to scientific literature are included. This manual is written in Chinese.

It is expressed in human HEK293 cells.
The protein purity is at least 95 % as measured by SDS‑PAGE and HPLC.
Store the dry product at 4 °C for up to 24 months; after reconstitution keep the solution at –20 °C for 6‑12 months and avoid repeated freeze‑thaw cycles.
The ED50 is reported as 1‑2.4 µg/ml in the cell adhesion assay.
