简单介绍
Recombinant Human IL-15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 Human IL-15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
|
Human
Interleukin-15 (IL-15) is expressed by the IL15 gene located on the
chromosome 4. It shares approximately 97% and 73% sequence identity with
simian and murine IL-15, respectively. Both human IL-15 and simian IL-15 are
active on murine cells. IL-15 is secreted by mononuclear phagocytes (and some
other cells), especially macrophages following infection by virus. It
possesses a variety of biological functions, including stimulating and
maintaining of cellular immune responses, especially regulating T and natural
killer (NK) cell activation and proliferation. In additionally, it shares
many biological properties with IL-2, including T, B and NK cell-stimulatory
activities. IL-15 signals through a complex composed of IL-2/IL-15 receptor
beta chain. Although IL-15 lacks sequence homology with IL-2, it has recently
been shown that both the beta and gamma chains of the IL-2 receptor are
utilized for IL-15 binding and signaling. In addition, an IL-15 specific
binding protein has also been cloned from a mouse T cell clone.

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。
