Recombinant Human IL-3 Protein (RP01362)

说明书 联系我们 收藏

Recombinant Human IL-3 Protein was determined by SDS-PAGE with Coomassie Blue, showing a band at 20-35kDa.

Recombinant Human IL3 promotes the proliferation of TF 1 human erythroleukemic cells. The ED50 for this effect is 1.5-6ng/mL.

Recombinant Human TPO(50 ng/mL, Cat. RP00174) , IL-3(15 ng/mL), IL-6(15 ng/mL, Cat. RP00201) and IL-11(15 ng/mL, Cat. RP00050) induce hematopoietic stem and progenitor cells to differentiate into megakaryocytes. After 6 days, the induction of CD41/42+ megakaryocytes was successful.(Customer feedback data)

描述
Recombinant Human IL-3 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Ala20-Phe152) of human interleukin-3/IL-3 (Accession #NP_000579.2) fused with a 6×His tag at the C-terminus.

纯度
> 95% by SDS-PAGE.
内毒素
< 1 EU/μg of the protein by LAL method.
生物活性
1.Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. The ED50 for this effect is 1.5-6 ng/mL.
2.Recombinant Human TPO(50 ng/mL, Cat. RP00174) , IL-3(15 ng/mL), IL-6(15 ng/mL, Cat. RP00201) and IL-11(15 ng/mL, Cat. RP00050) induce hematopoietic stem and progenitor cells to differentiate into megakaryocytes. After 6 days, the induction of CD41/42+ megakaryocytes was successful.
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

IL3 (interleukin 3), also known as IL-3, is a potent growth-promoting cytokine that belongs to the IL-3 family. IL3/IL-3 also belongs to the group of interleukins. Interleukins are produced by a wide variety of body cells. The function of the immune system depends in a large part on interleukins, and rare deficiencies of a number of them have been described, all featuring autoimmune diseases or immune deficiency. The majority of interleukins are synthesized by helper CD4+ T lymphocytes, as well as through monocytes, macrophages, and endothelial cells. They promote the development and differentiation of T, B, and hematopoietic cells. IL3/IL-3 is capable of supporting the proliferation of a broad range of hematopoietic cell types. It is involved in a variety of cell activities such as cell growth, differentiation, and apoptosis. IL3/IL-3 has been shown to also possess neurotrophic activity, and it may be associated with neurologic disorders.
