Background of Igf1
Insulin-like growth factor 1 (IGF-1) that was once called somatomedin C, is a polypeptide protein hormone similar in molecular structure to insulin. It plays an important role in childhood growth and continues to have anabolic effects in adults. Human IGF1 is a single chain 70-amino acid polypeptide cross-linked by 3 disulfide bridges, with a calculated molecular mass of 7.6 kD. The IGF1 gene, mapped on 12q22-q24.1, contains 5 exons. Exons 1-4 encode the 195-amino acid precursor (IGF1B), and exons 1, 2, 3, and 5 encode the 153-residue peptide (IGF1A). The structure of IGF1 resembles that of IGF2. And the IGF1 and IGF2 genes have complex structures with multiple promoters. The expression of both genes is regulated at the levels of transcription, RNA processing, and translation. IGF-1 is produced primarily by the liver as an endocrine hormone as well as in target tissues in a paracrine/autocrine fashion. Moreover, approximately 98% of IGF-1 is always bound to one of 6 binding proteins (IGF-BP). Furthermore, IGF-1 is one of the most potent natural activators of the AKT signaling pathway, a stimulator of cell growth and multiplication and a potent inhibitor of programmed cell death.

Question
Q: is it okay to use citrate plasma as samples in Rat IGF-I Picokine® ELISA Kit (Catalog # EK0377)?
Verified Customer
Verified customer
Asked: 2019-03-06
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of IGF-I causing disruption of its protein structure. IGF-I may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes required for detection and block the antigen antibody reaction. We have tested the IGF-I ELISA, treating samples with various anticoagulants and decided that heparin or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: What is the optimal O.D. value for IGF-I ELISA kit? I performed your IGF-I ELISA on serum samples. For my positive control, I received an O.D. value of 0.826, while my negative control received a value of 0.136. I obtained both of these controls from the ELISA kit, where your kit's typical data shows O.D. values much higher than my positive control and your background is lower. My samples O.D. values are around 0.225 and the highest is only 0.357. is it safe to say these samples contain IGF-I even though the O.D. values are not very high?
P. Zhang
Verified customer
Asked: 2018-02-01
Answer
A: The absolute O.D. values may change according to incubation time. The more you incubate the higher the O.D. values are going to be. an important assessment should be is whether your sample O.D. values are statistically significantly higher than your blank values. considering your assay, you could extend your development time in the substrate incubation step to obtain higher O.D. values, as long as your negative controls' O.D. values are not increasing faster in relation to your positive controls. normally, a sample with O.D. value 2 standard deviations higher than your negative controls can be considered positive. We calculate the sensitivity of this ELISA kit by changeing cutoff O.D. value, calculated as the average of 20 negative controls plus 2 standard deviations of the 20 negative controls, into a concentration. in other words, when we claim this IGF-I ELISA kit to have sensitivity of 5pg/ml, that means the minimum amount of IGF-I that can be declared/interpreted as positive by the above standard is 5pg/ml.

Asked: 2016-06-26
Answer
A: although the vials are bottled using aseptic techniques, heat-treated vials, and sterile stock solutions, they are not considered or guaranteed to be sterile. If sterile material is required for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: how to thaw whole blood sample for IGF-I ELISA after freezing?
W. Varma
Verified customer
Asked: 2014-06-28
Answer
A: we do not recommend freezing and thaw whole blood. erythrocytes are fragile and, if frozen and thawed, will undergo hemolysis rendering the samples useless. To keep your blood samples to test IGF-I for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.
