纯度
≥ 90 % as determined by SDS-PAGE.
内毒素
< 1 EU/μg of the protein by LAL method.
制剂
Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements.Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
描述
Recombinant Mouse IL-34 Protein is produced by HEK293 Cells expression system. The target protein is expressed with sequence (Met 1-Pro 235) of Mouse IL-34 (Accession # NP_001128572.1) fused with His tag at the C-terminus.
储存
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ 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。
生物活性
1. Immobilized Recombinant Rat CSF1R / MCSF Receptor / CD115 Protein (Fc Tag) at 2 μg/ml (100 μl/well) can bind Recombinant Mouse IL-34 Protein (His Tag), the EC50 is 1.5-4.5 ng/mL.2. Measured in a cell proliferation assay using M-NFS-60 mouse myeloid cells. The ED50 for this effect is typically 50-200 ng/mL.
复溶
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex 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。
请在蛋白复溶计算器中输入蛋白总质量和所需终浓度，快速计算您需要添加溶液的体积吧！
IL-34 is a cytokine that promotes the differentiation and viability of monocytes and macrophages through the colony-stimulating factor-1 receptor (CSF1R). IL-34 protein is expressed in various tissues, including heart, brain, lung, liver, kidney, spleen, thymus, testes, ovary, small intestine, prostate, and colon, and most abundant in the spleen. The colony-stimulating factor 1 receptor (CSF-1R) is identified as the receptor for IL-34.
