简单介绍
Recombinant Human TFF1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 TFF1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
|
Trefoil factor
1 belongs to the trefoil factor family that consists of three members named
TFF1, TFF2 and TFF3. They are characterized by having at least one copy of
the trefoil motif, a 40-amino acid domain that contains three conserved
disulfides. The TFFs are stable secretory proteins expressed highly in the
gastrointestinal tract (gastric mucosa). TFF1 is an essential protein for
normal differentiation of the antral and pyloric gastric mucosa and functions
as a stabilizer of the mucous gel overlying the gastrointestinal mucosa that
provides a physical barrier against various noxious agents. It is studied
because of commonly expressed in tumors as well.

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。
