简单介绍
Recombinant Human IGF-2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 IGF-2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
|
Insulin-like
growth factor (IGF)-I (also known as somatomedin C and somatomedin A) and
IGF-II (multiplication stimulating activity or MSA) belong to the family of
insulin-like growth factors that are structurally homologous to proinsulin.
Mature IGF-I and IGF-II share approximately 70% sequence identity. Both IGF-I
and IGF-II are expressed in many tissues and cell types and may have
autocrine, paracrine and endocrine functions. Mature IGF-I and IGF-II are
highly conserved between the human, bovine and porcine proteins (100%
identity), and exhibit cross-species activity.
The IGFL (insulin-like growth factor-like) family includes four small
(~11kDa), probably secreted family members in humans and one in mouse. This
family shares A and B chain cysteine motifs with the IGF superfamily, and has
an additional cysteine motif within an uncleaved region corresponding to the
C peptide of the IGF family.

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。
