[Abstract]
RIP1 does not mediate TNFα-induced apoptosis in RIP3 knockdown L929 cells. Nec-1 does not block the TNFα-induced death of RIP3 knockdown L929 cells. The cells are infected with the RIP3 shRNA or the negative control shRNA lentivirus, and western blotting is performed to determine RIP3 knockdown efficiency.

Description
Necrostatin-1 (Nec-1) is a potent and cross the blood-brain barrier necroptosis inhibitor with an EC50 of 490 nM in Jurkat cells. Necrostatin-1 inhibits RIP1 kinase (EC50=182 nM). Necrostatin-1 is also an IDO inhibitor[1].
IC50 & Target
EC50: 182 nM (RIP1 kinase)[1]
In Vitro
Necrostatin-1 (Nec-1) efficiently inhibits the TNFα-induced necrotic death of L929 cells, which does not require exogenous caspase inhibitors[1].
Necrostatin-1 (Nec-1) prevents radiocontrast media (RCM)-induced dilation of peritubular capillaries, suggesting a novel role unrelated to cell death for the RIP1 kinase domain in the regulation of microvascular hemodynamics and pathophysiology of contrast-induced AKI (CIAKI)[2].
Necrostatin-1 (Nec-1) (30 μM) increases the survival of cardiomyocyte progenitor cell (CMPCs) by inhibiting necrotic cell death[4].

Necrostatin-1 Related Antibodies
In Vivo
Necrostatin-1 (Nec-1) induces tubular bilation and affects the kinetics of the dilation of peritubular capillaries after RCM application. Upon a single intraperitoneal application of a single dose of Necrostatin-1 (1.65 mg/kg body weight, i.p.) 15 minutes before RCM, the return to baseline levels is prevented within the observation period[2].

*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, 1 year; -20°C, 6 months. When stored at -80°C, please use it within 1 year. When stored at -20°C, please use it within 6 months.
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.
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μLDMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μLDMSO stock solution (20.8 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.

For the following dissolution methods, please prepare the working solution directly.
It is recommended to prepare fresh solutions and use them promptly within a short period of time. 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.

Cell Assay
[3]
C6 (3×105 cells/well) and U87 (1.5×105 cells/well) glioma cells are seeded onto 96-well microplate and cultured 24 h. PBS is added into the control group and Shikonin is added into experimental group to reach the final concentration. Cellular viability is assessed using an MTT assay after Shikonin treatment at indicated time point. The absorbance value (A) at 570 nm is read using an automatic multi-well spectrophotometer. Two groups of glioma cells from the same cell line are treated with Shikonin at lower or higher concentration, respectively; other two groups of glioma cells are treated 1 h with 100 µM Necrostatin-1 or 40 µM z-VAD-fmk prior to co-incubation with Shikonin at indicated concentration. Additionally, another two groups of glioma cells are treated only with 100 µM Necrostatin-1 or 40 µM Z-VAD-fmk at corresponding time point[3].

Animal Administration
Mice[2]
8-10 week old male C57BL/6 mice (average weight approx.23 g) are used. Mice receive intravenous application of 200 μL PBS or radiocontrast media (RCM) via the tail vein. A single dose of Z-VAD-fmk (10 mg/kg body weight) or Necrostatin-1 (1.65 mg/kg body weight) is applied intraperitoneally 15 min. before RCM-injection. Mice are harvested another 24 hours after RCM-application (48 hours after reperfusion). Blood samples are obtained from retroorbital bleeding and serum levels of urea and creatinine are determined.

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.
