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

Cat. No.: HY-P704506
Handling Instructions Technical Support

Claudin-3/CLDN3 proteins play a critical role in tight junctions, eliminating intercellular spaces through calcium-independent cell adhesion activity. It exhibits multifunctionality by forming homo- and heteropolymers with other CLDN members, including CLDN1 and CLDN2. Claudin-3/CLDN3 Protein-VLP, Human (HEK293) is the recombinant human-derived Claudin-3/CLDN3 protein, expressed by HEK293, with tag free.Formed in HEK293 cultures, these VLPs concentrate membrane proteins on the cell surface, producing high-concentration proteins ideal for immunization and antibody screening. Given the high immunogenicity of VLPs, the immunization protocol such as antigen dose, schedule, and adjuvant, requires optimization. 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-P705433.

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
