Claudin-3/CLDN3 Protein-VLP, Human (HEK293, His)

Customer Review

Based on 1 Customer Validation

Claudin-3/CLDN3 Protein-VLP, Human (HEK293, His) is recommended for animal immunization, ELISA. It is not recommended for receptor-ligand interaction detection and SPR/BLI assay since there are other irrelevant membrane proteins of the host on the VLP envelope, and the receptor-ligand interaction will have strong background interference. High requirements for chips and experimental protocols are needed for SPR/BLI assays. If VLP control is required, it is recommended HY-P701236. Tags can only be detected under denaturing conditions.

For research use only. We do not sell to patients.

Description

Claudin-3/CLDN3 Protein-VLP, Human (HEK293, His) is recommended for animal immunization, ELISA. It is not recommended for receptor-ligand interaction detection and SPR/BLI assay since there are other irrelevant membrane proteins of the host on the VLP envelope, and the receptor-ligand interaction will have strong background interference. High requirements for chips and experimental protocols are needed for SPR/BLI assays. If VLP control is required, it is recommended HY-P701236. Tags can only be detected under denaturing conditions.

Background

Claudin-3/CLDN3 Protein assumes a crucial role in the specific obliteration of the intercellular space within tight junctions, employing calcium-independent cell-adhesion activity. This protein demonstrates its versatility by forming both homo- and heteropolymers with other CLDN members, including interactions with CLDN1 and CLDN2 homopolymers. Additionally, Claudin-3/CLDN3 directly engages with tight junction-associated proteins TJP1/ZO-1, TJP2/ZO-2, and TJP3/ZO-3, emphasizing its integral role in the assembly and maintenance of tight junction complexes. The ability to form polymers and interact with key junctional components highlights Claudin-3/CLDN3's significance in regulating cell adhesion and the structural integrity of intercellular spaces.

Verified Bioactivity

Measured by its binding ability in a functional ELISA. Immobilized Human CLDN3 at 10 μg/mL can bind Anti-CLDN3 recombinant antibody, the EC50 is <34.37 ng/mL.VLPs is negative control.
