About this protein | |
Name | Recombinant Human IL-20 (Recombinant Human Interleukin-20; rHuIL-20);重組人白細(xì)胞介素20 |
Synonyms | Cytokine Zcyto10; IL10D; IL-20ZCYTO10four alpha helix cytokine; interleukin 20; interleukin-20; MGC96907 |
Purity | >95% 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 IL-20Rα and human IL-20Rβ co-transfected murine BaF3 pro-B cells is less than 0.5ng/ml, corresponding to a specific activity of >2.0×106IU/mg. |
Physical Appearance | Sterile Filtered lyophilized (freeze-dried) liquid-like powder. |
Formulation | Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.2, with trehalose. |
Endotoxin | Less than 1EU/μg of rHuIL-20 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 | Human Interleukin-20 (IL-20) is encoded by the IL20 gene located on the chromosome 1 and belongs to the IL-10 family that including IL-10, IL-19, IL-22, IL-24, and IL-26. It is secreted by activated keratinocytes and monocytes, and signals through two distinct cell-surface receptor complexes on keratinocytes and other epithelial cells. IL-20 has functions of regulating proliferation and differentiation of keratinocytes during inflammation, and causing cell expansion of multipotential hematopoietic progenitor cells. |

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(huì)引起部分失活,所以首次配制成相應(yīng)濃度的儲(chǔ)存液后(請(qǐng)根據(jù)產(chǎn)品簡(jiǎn)介中Reconstitution一欄的信息配制儲(chǔ)存液),須分裝后-20℃或更低溫度凍存,以避免反復(fù)凍融。
注意事項(xiàng):
???????由于有些塑料管壁對(duì)某些蛋白有較強(qiáng)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(yù)先封閉塑料管壁上的蛋白結(jié)合位點(diǎn),使細(xì)胞因子或重組蛋白不會(huì)粘附于管壁。所以一定要使用產(chǎn)品簡(jiǎn)介中Reconstitution一欄的信息配制儲(chǔ)存液。
???????本產(chǎn)品在凍干時(shí)添加了海藻糖作為保護(hù)劑,此時(shí)凍干后本產(chǎn)品看起來(lái)仍然像是液體,屬于正常現(xiàn)象。在凍干工藝上,海藻糖作為常用的凍干保護(hù)劑,可顯著阻止蛋白質(zhì)二級(jí)結(jié)構(gòu)的改變,防止凍干過(guò)程中的蛋白變性。
???????本產(chǎn)品僅限于專業(yè)人員的科學(xué)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(nèi)。
???????為了您的安全和健康,請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
