简单介绍
Recombinant Human PF-4/CXCL4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 PF-4/CXCL4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
|
Platelet
Factor-4 (PF-4) is a small cytokine belonging to the CXC chemokine family
that is also known as chemokine (C-X-C motif) ligand 4 (CXCL4). The gene for
human CXCL4 is located on human chromosome 4. This chemokine is released from
alpha-granules of activated platelets during platelet aggregation and
neutralizes the anticoagulant effect of heparin. It interacts with a splice
variant of the chemokine receptor CXCR3 besides be chemotactic for
neutrophils, fibroblasts and monocytes. Recombinant human CXCL4 contains 70
amino acids binds with high affinity to heparin. Specifically, Human and
mouse CXCL4 share about a 60% identity.

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。
