Background: IGF-I/IGF-1

Insulin-like Growth Factor 1 (IGF-1), also known as somatomedin C, is a member of the insulin superfamily. It was originally discovered as a mediator of growth hormone actions on somatic cell growth, but has also been shown to be an important regulator of cell metabolism, differentiation and survival. IGF-1 is synthesized as a preproprotein that is proteolytically cleaved to generate the mature protein linked by three disulfide bonds. Mature IGF-1 is highly conserved among large mammals, with 100% sequence identity between the human, bovine, porcine, equine, and canine proteins. 

Mature mouse IGF-1 is a non-glycosylated, 70 amino acid (aa) secreted polypeptide that is derived from either a 153 aa or a 159 aa preproprotein. It shares 99% and 94% aa sequence identity with rat and human IGF-1, respectively. IGF-1 is synthesized in the liver and other tissues. It is found in blood and other body fluids as a complex with specific high affinity IGF binding proteins (IGFBP-1 to -6). The IGFBPs are expressed in specific patterns during development. They are modulators of IGF actions, which control IGF bioavailability to specific cell-surface receptors. Their functions are further regulated by IGFBP proteases, which proteolytically cleave the IGFBPs to lower the affinity with which they bind IGFs and increase IGF bioavailability. Some IGFBPs also have IGF-Independent effects on cell functions. IGF-Independent circulates primarily as a ternary complex with IGFBP-3 or IGFBP-5 and the acid-labile subunit (ALS). Some IGF-1 is also present in binary complexes with other IGFBPs. Whereas the ternary complexes are generally restricted to the vasculature, the binary complexes freely enter the tissues. 

IGF-1 actions are mediated by two ubiquitously expressed receptor tyrosine kinases: IGF-I R and Insulin R/CD220. IGF-I R and Insulin R are disulfide-linked heterotetrameric complexes that consist of two alpha and two beta subunits. For both of these receptors, the prepro proteins are cleaved to produce extracellular alpha subunits which contain a cysteine-rich region and ligand-binding fibronectin type III (FN-III) domains, and beta subunits which contain an extracellular FN-III domain, transmembrane, and cytoplasmic tyrosine kinase domains. A hybrid complex containing one IGF-I R and one Insulin R also serves as a functional high affinity receptor for IGF-1. IGF-I R-Insulin R hybrids respond primarily to IGF-1, potentially downregulating the cellular response to Insulin. IGF signaling is also modulated by IGF binding proteins and the scavenger receptor, IGF-I I R.

Assay Procedure


Plate Preparation

  1. Dilute the Capture Antibody to the working concentration in PBS without carrier protein. Immediately coat a 96-well microplate with 100 μL per well of the diluted Capture Antibody. Seal the plate and incubate overnight at room temperature.
  2. Aspirate each well and wash with Wash Buffer, repeating the process two times for a total of three washes. Wash by filling each well with Wash Buffer (400 μL) using a squirt bottle, manifold dispenser, or autowasher. Complete removal of liquid at each step is essential for good performance. After the last wash, remove any remaining Wash Buffer by aspirating or by inverting the plate and blotting it against clean paper towels.
  3. Block plates by adding 300 μL of Reagent Diluent to each well. Incubate at room temperature for a minimum of 1 hour.
  4. Repeat the aspiration/wash as in step 2. The plates are now ready for sample addition.

Assay Procedure

  1. Add 100 μL of sample or standards in Reagent Diluent, or an appropriate diluent, per well. Cover with an adhesive strip and incubate 2 hours at room temperature.
  2. Repeat the aspiration/wash as in step 2 of Plate Preparation.
  3. Add 100 μL of the Detection Antibody, diluted in Reagent Diluent, to each well. Cover with a new adhesive strip and incubate 2 hours at room temperature.
  4. Repeat the aspiration/wash as in step 2 of Plate Preparation.
  5. Add 100 μL of the working dilution of Streptavidin-HRP to each well. Cover the plate and incubate for 20 minutes at room temperature. Avoid placing the plate in direct light.
  6. Repeat the aspiration/wash as in step 2.
  7. Add 100 μL of Substrate Solution to each well. Incubate for 20 minutes at room temperature. Avoid placing the plate in direct light.
  8. Add 50 μL of Stop Solution to each well. Gently tap the plate to ensure thorough mixing.
  9. Determine the optical density of each well immediately, using a microplate reader set to 450 nm. If wavelength correction is available, set to 540 nm or 570 nm. If wavelength correction is not available, subtract readings at 540 nm or 570 nm from the readings at 450 nm. This subtraction will correct for optical imperfections in the plate. Readings made directly at 450 nm without correction may be higher and less accurate.
