| About this protein | |
| Name | Recombinant Human IL-5 (Recombinant Human Interleukin-5; rHuIL-5);重組人白細胞介素5 |
| Synonyms | BCDF mu; BCGFII; EDF; Eo-CSF; TRF; B-cell differentiation factor I; EDF; Eosinophil differentiation factor; IL-5T-cell replacing factor; interleukin 5 (colony-stimulating factor, eosinophil); interleukin-5; TRFB cell differentiation factor I |
| Purity | >98% by SDS-PAGE and HPLC analyses. |
| Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by a cell proliferationassay using human TF-1 cells is less than 0.1ng/ml, corresponding to a specific activity of >1.0×107IU/mg. |
| Physical Appearance | Sterile Filtered lyophilized (freeze-dried) liquid-like powder. |
| Formulation | Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH7.5, 3% trehalose, 0.1% Tween-80. |
| Endotoxin | Less than 1EU/μg of rHuIL-5 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 | The IL-5 gene is located on chromosome 5 in humans, in close proximity to the genes encoding IL-3, IL-4, and granulocytemacrophage colony-stimulating factor (GM-CSF), which are often co-expressed in TH2 cells. Through binding to the IL-5 receptor, IL-5 stimulates B cell growth and increases immunroglobulin secretion. It is also a key mediator in eosinophil activation. Interleukin-5 has long been associated with the cause of several allergic diseases including allergic rhinitis and asthma. IL-5 is a 115-amino acid (in human, 133 in the mouse) -long TH2 cytokine that is part of the hematopoietic family. Unlike other members of this cytokine family (namely IL-3 and GM-CSF), this glycoprotein in its active form is a homodimer. |

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。
???????本產品在凍干時添加了海藻糖作為保護劑,此時凍干后本產品看起來仍然像是液體,屬于正?,F象。在凍干工藝上,海藻糖作為常用的凍干保護劑,可顯著阻止蛋白質二級結構的改變,防止凍干過程中的蛋白變性。
???????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。
