简单介绍
Recombinant Human FGF-21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 FGF-21所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

biologically active when compared to standard. The ED50 as determined by
thymidine uptake assay using FGF-receptors transfected BaF3 cells is less
than 0.5μg/ml, corresponding to a specific activity of >2.0×103IU/mg in the presence of 5μg/ml
of rMuKlotho-β and 10μg/ml of
heparin.

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
|
Fibroblast
growth factor-21 (FGF-21) belongs to the large FGF family which is encoded by
the FGF-21 gene and it is specifically induced by HMGCS2 activity. All FGF
family members are heparin binding growth factors with a core 120 amino acid
(a.a.) FGF domain that allows for a common tertiary structure and they are
involved in a variety of biological processes including embryonic
development, cell growth, morphogenesis, tissue repair, tumor growth and
invasion. FGF-21 stimulates glucose uptake in differentiated adipocytes via
the induction of glucose transporter SLC2A1/GLUT1 expression (but not
SLC2A4/GLUT4 expression) and the activity depends on the presence of KLB.
FGF-21 contains a 28a.a. signal sequence and a 181a.a. mature region but show
limited binding to heparin. In addition, Mature human FGF-21 respectively
shows 81%a.a. identity to murine and rat FGF-21, and is known to be active on
murine 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。
