| 蛋白构建 | 1-297 aa |
| 蛋白纯度 | > 90% as determined by SDS-PAGE. |
| 分子量 | 40.4 kDa (predicted) |
| 内毒素 | < 1.0 EU/μg of the protein as determined by the LAL method. |
| 缓冲液 | If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. |
| 复溶方法 | Reconstitute the lyophilized protein in sterile deionized 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 | 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. Solutions are shipping with dry ice. |
| 研究背景 | Pore-forming toxin that defensively acts against parasitic microorganisms by forming pores in sphingomyelin-containing membranes. Has hemolytic activity and is also cytotoxic to spermatozoa of some species of invertebrates and many species of vertebrates and to amphibian larvae, guinea pig polymorphonuclear leukocytes, chicken fibroblasts, normal spleen cells and various tumor cells. Is lethal for various species of reptiles, amphibian, birds and mammals. Induces smooth muscle contraction. It binds sphingomyelin and induces hemolysis in the same manner as lysenin-related protein 2, and is 10-fold more effective than lysenin-related protein 1. |
