简单介绍
Recombinant Human IL-7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��)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-7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
|
Interleukin-7
(IL-7) is encoded by the IL7 gene and secreted by stromal cells in the red
marrow and thymus. It binds to the IL-7 receptor, a heterodimer consisting of
IL-7 receptor alpha and IL-2 receptor gamma chain. IL-7 stimulates the
differentiation of hematopoietic stem cells into lymphoid progenitor cells
and also stimulates proliferation of B cells, T cells and NK cells. Murine
IL-7 has approximately 65% amino acid sequence identity with human IL-7 and
both proteins exhibit cross-species activity. IL-7 as an immunotherapy agent
has been examined in many human clinical trials for various malignancies and
during HIV infection.

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。
