Hydrostatin-TL1
Based on 1 Customer Validation
Hydrostatin-TL1 (H-TL1), a nine-amino-acid peptide, is a TNF-α antagonist. Hydrostatin-TL1 can be isolated from the venom gland of sea snake Hydrophis cyanocinctus. H-TL1 competitively inhibits the interaction between TNF-α/TNFR1 and attenuates the cytotoxicity and inflammation of TNF-α. Hydrostatin-TL1 can be used for TNF-α-associated inflammatory diseases, such as rheumatoid arthritis, osteoporosis and inflammatory bowel disease (IBD) research.

In Vitro
Hydrostatin-TL1 (1-1000 nM, 18-20 h) inhibits TNF-α-induced L929 cells death in a concentration-dependent manner [1].
Hydrostatin-TL1 (0.2-1.6 μM) significantly inhibits the TNF-α-induced phosphorylation of p38, ERK, JNK, and IκB protein within the NF-κB and MAPKs signaling pathways in HEK-293 cells[1].
Hydrostatin-TL1 fails to inhibit the phosphorylation of IκB induced by IL-1β in HEK-293 cells[1].
Hydrostatin-TL1 (0.1-0.8 nM) dose-dependently reduces TNF-α-mediated mRNA expression of pro-inflammatory factors (IL-8, TNF-α, ICAM-1, and VCAM-1) in HEK-293 cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Hydrostatin-TL1 (20-80 μg/kg, three times at 1, 3 and 5 h) dose-dependently reduces mortality in LPS (HY-D1056)-induced acute shock mice model[1].

용액&용해도
In Vitro:
DMSO : 25 mg/mL (26.76 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (2.68 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
