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.

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. |
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℃. 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. |
