HY-100987

Lauroylcarnitine chloride	Biochemical Assay Reagents	Others
Lauroylcarnitine chloride enhances the absorption of salmon calcitonin in rats. Also in determining in situ bioavailability, increased availability of Lucifer yellow and decreased expression of claudin-4 protein in the colon .

HY-P11785

Cpe30 MT2	Claudin	Cancer
Cpe30 MT2 is a short peptide that binds tightly junction protein Claudin‑4 (CLDN4) with high affinity, with a K_d value of 1.97 nM. Cpe30 MT2 can be used for the synthesis of PET molecular imaging probes targeting pancreatic cancer .

HY-N17783A

Sanleng acid	Endogenous Metabolite	Inflammation/Immunology
Sanleng acid is an unsaturated fatty acid compound that can be isolated from the hexane extract of Magnolia sieboldii (MsHE). MsHE can inhibit the expression of inflammatory mediators (such as COX-2) and pro-inflammatory cytokines (such as TNF-α, IL-1β), and increase the expression of tight junction proteins (claudin-4, *claudin-5*) to protect epithelial cell barrier function, thus exerting anti-inflammatory activity. Related compounds may be used in research related to reflux esophagitis (RE).

	Claudin-4/CLDN4 Protein-VLP, Human (HEK293, His) CLDN4; Claudin 4; CPETR, CPETR1; Claudin-4; Clostridium perfringens enterotoxin receptor 1; CPE R; hCPE R; WBSCR8; Williams Beuren syndrome chromosomal region 8 protein;	Human	HEK293
	Claudin-4/CLDN4 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.

	Claudin-4/CLDN4 protein-VLP is a channel-forming tight junction protein that promotes paracellular chloride transport in the kidney. It is essential for the reabsorption of filtered chloride in the collecting duct. Claudin-4/CLDN4 Protein-Nanodisc, Human (HEK293,His, Strep) is the recombinant human-derived Claudin-4/CLDN4 protein, expressed by HEK293, with C-Strep and N-His labeled tag.
