Background of IGF-I/IGF-1

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.1 The IGF1 gene, mapped on 12q22-q24. 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.

12 Customer Q&As for Mouse IGF-1 ELISA Kit PicoKine®


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?

Verified Customer

Verified customer

Asked: 2020-09-29


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. what you should focus on is whether your sample O.D. values are statistically significantly higher than your blank values. in your example, 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 proportion to your positive controls. typically, 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 converting 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.

I want to purchase the EK0378 Mouse IGF-1 ELISA Kit. I read the catalog and it stated that the assay is used for free IGF1 measurement. I want to ask whether IGFBPs interference have been tested for this assay? You have previous validation data about this issue? Can you share it with me? Other companies suggests that IGFBPs interfere IGF1 measurement significantly.

Q: Can IGF-I ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

Verified Customer

Verified customer

Asked: 2019-04-26


A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not valid for other sample types than we have tested: it means further investigation is required. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been evaluated by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please check the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring IGF-I using the EK0378 Mouse IGF-I Picokine® ELISA Kit?

M. Clark

Verified customer

Asked: 2019-03-17


A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample immediately after collection when possible, or aliquot into single use volumes and store samples frozen. avoid repeat freeze-thaw cycles with the stored samples in order to prevent protein degradation.

As it is illustrated in the kit protocol, the desired concentration of the target protein should fall within the standard curve (63.5pg/ml -4000pg/ml). However, my biggest concern is that I am not sure about the concentration of the target protein in my serum sample, therefore I don

We can not provide extra well strips because it is useless to provide extra strips without providing extra other components in the whole package. Running pilot test to figure out the optimal dilution ratio is a part of the whole experiment. Our suggested dilution ratio for serum from healthy mouse is 1:10-1:100.

Boster Scientific Support

Answered: 2017-08-31


In your instructions you state that 98% of the IGF-1 produced is bound by IGF binding proteins but the standard in your kit is purified recombinant material. Do the antibodies in your kit binding IGF-1 when it is bound to binding proteins or is your kit just measuring the 2% of the IGF that isn't bound to binding proteins? If one wanted to measure total IGF-1, how would you recommend one prepare the serum and plasma samples, let alone the cell supernatants? Does this ELISA work with RIPA treated samples for instance and if so do you have any data? Keyword: applications, protocol, detection

Q: how can I thaw whole blood sample for IGF-I ELISA after freezing?

C. Thompson

Verified customer

Asked: 2014-09-02


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.
