Immunohistochemical analysis of IGF-I expression in NZ rabbit knee joint tissue.
Cat# RPA01343 was used as primary antibody, dilution 1:200.
Polyclonal IGF-I antibody was produced from sera of rabbits immunized with synthetic protein containing IGF-1 antigenic determinants.
Serum IgG fraction was purified by Protein A affinity chromatography.
Lyophilized from sterile filtered PBS solution at a concentration of 1mg/ml.
A quick spin of the vial followed by reconstitution in distilled water. This solution can then be diluted into other buffers
The lyophilized antibody is stable for at least 1 year from date of receipt at -20° C.
Upon reconstitution, this antibody can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months without detectable loss of activity.
Avoid repeated freeze/thaw cycles.

Insulin-like growth factor
I, also known as somatomedin
C, is the dominant effector
of growth hormone and is
structurally homologous to
proinsulin. Human IGF-I is
synthesized as two precursor
isoforms with N- and
alternate C- terminal
propeptides (1). These
isoforms are differentially
expressed by various tissues
(1). The 7.6 kDa mature IGF-
I is identical between
isoforms and is generated by
proteolytic removal of the
N- and C- terminal regions.
Mature human IGF-I shares
94% and 96% aa sequence
identity with mouse and rat
IGF-I, respectively (2), and
activity. It shares 64% aa
sequence identity with
mature human IGF-II.
Circulating IGF-I is
produced by hepatocytes,
while local IGF-I is
produced by many other
tissues in which it has
