Purity | >98% by SDS-PAGE and HPLC analyses. |
Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 0.2ng/ml, corresponding to a specific activity of >5.0×106IU/mg. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4. |
Endotoxin | Less than 1EU/μg of rHuIL-4 as determined by LAL method. |
Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions. |
Category | Cytokine |
Background | Interleukin-4 (IL-4) is a pleiotropic cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells and produced by mast cells, activated T cells and bone marrow stromal cells. It has many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of CD4+ T-cells into Th2 cells. It enhances both secretion and cell surface expression of IgE and IgG1 and also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. The human IL-4 has a compact, globular fold, stabilised by 3 disulphide bonds. The human IL-4 shares about 40%a.a. sequence identity with mouse/rat IL-4 and they are species-specific in their activities. Manufactured using all Animal-Free reagents. |

保存條件:
???????-20℃或更低溫度保存,至少一年有效。由于蛋白的每次凍融均會引起部分失活,所以首次配制成相應濃度的儲存液后(請根據(jù)產品簡介中Reconstitution一欄的信息配制儲存液),須分裝后-20℃或更低溫度凍存,以避免反復凍融。
注意事項:
???????由于有些塑料管壁對某些蛋白有較強的吸附作用,溶液中的蛋白很容易粘附在管壁上,并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein,如0.1% BSA等)的主要作用是預先封閉塑料管壁上的蛋白結合位點,使細胞因子或重組蛋白不會粘附于管壁。所以一定要使用產品簡介中Reconstitution一欄的信息配制儲存液。
???????本產品僅限于專業(yè)人員的科學研究用,不得用于臨床診斷或治療,不得用于食品或藥品,不得存放于普通住宅內。
???????為了您的安全和健康,請穿實驗服并戴一次性手套操作。
