Purity of CLDN18.2, hFc, Human (Cat. No. Z03709) was assessed by coomassie stained SDS-PAGE. Purity ≥ 75% was observed for 2 μg of protein.
Lane 1: 2 μg of Z03709, under reducing (R) conditions, no heat treatment before loading.
Lane 2: 2 μg of Z03709, under non-reducing (N) conditions.
The two arrows point to the bands corresponding to CLDN 18.2 protein which run in the gel with two distinct molecular weights, typical anomalous SDS-PAGE migration of membrane proteins.
Target Background |
Claudin-18 is a protein that in humans is encoded by the CLDN18 gene. CLDN18 belongs to the large claudin family of proteins, which form tight junction strands in epithelial cells. The Expression of Isoform A2 (CLDN18.2) is restricted to the stomach mucosa where it is predominantly observed in the epithelial cells of the pit region and the base of the gastric glands including exocrine and endocrine cells (at protein level). CLDN18.2 is founded to be abundant in gastric tumors, Experimental antibody IMAB362 targets Claudin 18.2 to help treat gastric cancers. |
