简单介绍
Recombinant Equine IL-2 Cys141Ser由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。Recombinant Equine IL-2 Cys141Ser所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

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.

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.

保存条件:
-20℃或更低温度保存，至少一年有效。由于蛋白的每次冻融均会引起部分失活，所以**配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液)，须分装后-20℃或更低温度冻存，以避免反复冻融。
注意事项:
由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。
