Function

Required for the formation of the gastric paracellular barrier via its role in tight junction formation, thereby involved in the response to gastric acidification.

Biological Context

Subcellular Location: Cell junction, tight junction; Lateral cell membrane
Tissue Specificity: Expression 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)

Product Specifications

Recombinant Human Claudin-18.2 (CLDN18.2)-VLPs, Fluorescent (Active) is a recombinant protein from Homo sapiens (Human), expressed in Mammalian cell, covering amino acids 1-261aa, with C-terminal mCherry-tagged tag, molecular weight 52.3 kDa. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

Western Blot: Compatible with standard Western Blot protocols.

Protein Interaction: Validated for SPR (Surface Plasmon Resonance) and BLI (Bio-Layer Interferometry) studies.

Shipping: Shipped at ambient temperature. Lyophilized protein is stable during transit.

Storage: Store lyophilized protein at -20°C to -80°C. Reconstituted protein should be aliquoted and stored at -80°C. Avoid repeated freeze-thaw cycles.
