IL-4 Protein, Human, Recombinant (His & Avi)

产品编号 TMPK-00034

Interleukin-4, also known as IL4, is a secreted protein which belongs to the IL-4 / IL-13 family. Interleukin-4 / IL4 has many biological roles, including the stimulation of activated B-cell and T-cell proliferation.In the presence of IL-4 and IL-13, cytokines that are produced in a Th-2 type response, particularly during allergy and parasitic infections, macrophages become differentially activated, And this cytokine is a ligand for interleukin 4 receptor. . IL-4 Protein, Human, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 17.8 kDa and the accession number is P05112.

生物活性	1. Immobilized Human IL-4 at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Human IL-4 R alpha, hFc Tag with the EC50 of 18.4ng/ml determined by ELISA (QC Test). 2. Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. The ED50 for this effect is <0.2 ng/mL.

蛋白构建	His25-Ser153
蛋白纯度	> 95% as determined by Tris-Bis PAGE
分子量	17.8 kDa (predicted). Due to glycosylation, the protein migrates to 23-25 kDa based on Tris-Bis PAGE result.
内毒素	< 1 EU/μg by the LAL method.
蛋白性状	Lyophilized powder
缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
复溶方法	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
存储	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式	In general, Lyophilized powders are shipping with blue ice.
