About this protein
Name
Recombinant Human IL-2 (Recombinant Human Interleukin-2; rHuIL-2);重組人白細(xì)胞介素2
Synonyms
aldesleukin; Aldesleukin; IL-2lymphokine; interleukin 2; interleukin-2; involved in regulation of T-cell clonal expansion; T cell growth factor; T-cell growth factor; TCGF
Purity
>97% 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 murine CTLL-2 cells is less than 0.1ng/ml, corresponding to a specific activity of >1.0×107IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH5.0.
Endotoxin
Less than 1EU/μg of rHuIL-2 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 H2O 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. Do not reconstitute in cell culture media directly.

Background
IL-2 is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. It is expressed by CD4+ and CD8+ T cells, γδ T cells, B cells, dendritic cells and eosinophils. IL-2/IL-2R signaling is required for T-cell proliferation and other fundamental functions which are essential for the immune response. The receptor for IL-2 consists of three subunits (55kDa IL-2Rα, 75kDa IL-2Rβ, and 64kDa common gamma chain γc/IL-2Rγ) that are present on the cell surface in varying preformed complexes. Mature human IL-2 shares 56% and 66% amino acid sequence identity with mouse and rat IL-2, respectively. Human and mouse IL-2 exhibit cross-species activity.

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**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**于專業(yè)人員的科學(xué)研究用,不得用于臨床診斷或**,不得用于食品或藥品,不得存放于普通住宅內(nèi)。 為了您的**和健康,請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
