Recombinant Human CSF-2/GM-CSF Protein (RP00094)

Recombinant Human CSF-2/GM-CSF Protein was determined by SDS-PAGE with Coomassie Blue, showing a band at 20-32 kDa.

Recombinant Human CSF-2 stimulates cell proliferation of the TF‑1 human erythroleukemic cells. The ED50 for this effect is 30-140 pg/mL, corresponding to a specific activity of 7.14×106-3.33×107units/mg.

描述
Recombinant Human CSF-2/GM-CSF Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Ala18-Glu144) of human GM-CSF/CSF2 (Accession #NP_000749.2) fused with a 6×His tag at the C-terminus.

< 0.1 EU/μg of the protein by LAL method.
生物活性
Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. The ED50 for this effect is 30-140 pg/mL, corresponding to a specific activity of 7.14×106-3.33×107units/mg.
制剂
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
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

The protein encoded by this gene is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of the protein is found extracellularly as a homodimer. This gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13.
