About this Antibody
Name
Recombinant Equine IL-2 Cys141Ser (Recombinant Equine Interleukin-2 Cys141Ser; rEqIL-2 Cys141Ser)；重組馬白細(xì)胞介素2 Cys141Ser
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 1.0μg/ml, corresponding to a specific activity of >1000IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH6.5.
Endotoxin
Less than 0.1EU/μg of rEqIL-2 Cys141Ser 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.

Cytokine
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 IL2Rα, 75kDa IL2Rβ, 64kDa common gamma chain γc/IL2Rγ) that are present on the cell surface in varying preformed complexes. Recombinant equine IL-2 is a 14.9kDa protein containing 129 amino acid residues. At the amino acid sequence level, equine IL-2 shares 72%, 70%, 56% and 54% sequence similarities with human, porcine, rat and murine IL-2, respectively. It has been reported that equine IL-2 augmented proliferation in equine peripheral blood mononuclear cells, but has no effect on murine CTLL2 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引起部分失活，所以**配制成相應(yīng)濃度的儲存液后(請根據(jù)產(chǎn)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(fù)凍融。 注意事項(xiàng): 由于有些塑料管壁對某些蛋白有較強(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粘附于管壁。所以一定要使用產(chǎn)品簡介中Reconstitution一欄的信息配制儲存液。 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，請穿實(shí)驗(yàn)服并戴一次性手套操作。
