EpCAM/TROP1 Protein, Human, Recombinant (aa 24-265, His)

Epithelial Cellular Adhesion Molecule (EpCAM), also known as KS1/4, gp40, GA733-2, 17-1A, and TROP‑1, is a 40 kDa transmembrane glycoprotein that consists of a 242 amino acid (aa) extracellular domain with two EGF‑like repeats, a 23 aa transmembrane segment, and a 26 aa cytoplasmic domain. EpCAM/TROP1 Protein, Human, Recombinant (aa 24-265, His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 28.2 kDa and the accession number is P16422.

Description

Species	Human
Expression System	HEK293 Cells
Tag	C-His
Accession Number	P16422
Synonyms	DIAR5, MOC31, EGP, MK1, HNPCC8, EGP314, ESA, MIC18, TROP1, EGP40, EpCAM, TACSTD1, gp40, CD326, TACST-1, EGP-2, ACSTD1, KSA
Construction	Gln24-Lys265
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	28.2 kDa (predicted). Due to glycosylation, the protein migrates to 30-45 kDa based on Tris-Bis PAGE result.

Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
