Active Recombinant Mouse IL-1 beta Protein (RP01340)

Recombinant Mouse IL-1 beta Protein was determined by SDS-PAGE with Coomassie Blue, showing a band at showing bands at 19-20 kDa..

Immobilized Mouse IL1B at 10 μg/mL (100 μL/well) can bind Human IL1R2 with a linear range of 0.03125-0.8036 μg/mL.

Recombinant Mouse IL-1B promotes the proliferation of D10.G4.1 mouse helper T cells. The ED50 for this effect is 42.1-168.4 pg/mL, corresponding to a specific activity of 5.94×106-2.37×107units/mg.

纯度
> 95% by SDS-PAGE.
内毒素
< 1 EU/μg of the protein by LAL method.
生物活性
1.Measured by its binding ability in a functional ELISA. Immobilized Mouse IL1B at 10 μg/mL (100 μL/well) can bind Human IL1R2 with a linear range of 0.03125-0.8036 μg/mL.
2.Measured in a cell proliferation assay using D10.G4.1 mouse helper T cells. The ED50 for this effect is 42.1-168.4 pg/mL, corresponding to a specific activity of 5.94×106-2.37×107units/mg.
制剂
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
储存
Store the lyophilized protein at -20°C to -80°C for long term.
After reconstitution, the protein solution is stable at -20°C for 3 months, at 2-8°C for up to 1 week.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月;
复溶之后,蛋白溶液在-20°C及以下可保存3个月,在2-8℃可保存1周。
复溶
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底,如果粉末浮起,开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL(请注意蛋白复溶浓度不能低于0.1 mg/mL),室温平衡5-10 min保证充分溶解,复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存,建议复溶时添加载体蛋白或者稳定剂(如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖),同时将复溶后的蛋白溶液按照需求进行分装,储存于-20°C至-80°C,随取随用,避免反复冻融。

背景信息

Interleukin-1 beta (IL1 beta or IL1B) also known as catabolin, is a member of the interleukin 1 cytokine family.This cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis. The induction of cyclooxygenase-2 (PTGS2/COX2) by this cytokine in the central nervous system (CNS) is found to contribute to inflammatory pain hypersensitivity.
