产品概述
Human IGF1 ELISA kit has been re-developed. We have identified new recombinant monoclonal antibodies to provide improved performance and consistency.
Human IGF1 ELISA Kit (ab211651) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of IGF1 protein in serum, cell culture media, cit plasma, edta plasma, and hep plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human IGF1 with 11.97 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
ASSAY SPECIFICITY This kit recognizes both native and recombinant human IGF1 protein in serum, plasma, and cell culture supernatant samples only. Cell and tissue extract samples have not been tested with this kit.
This kit is incompatible with cell culture supernatant samples than contain bovine serum.
CROSS REACTIVITY Recombinant human IGF2 and IGFBP3 were prepared at 16000 and 8000 pg/mL and assayed for cross reactivity. No cross-reactivity was observed.
INTERFERENCE Recombinant IGF1 and IGFBP3 were prepared at 12000 pg/mL and 12000 p/mL and tested for interference. No interference with was observed.
SPECIES REACTIVITY This kit recognizes human IGF1 protein. Other species reactivity was determined by measuring 1.25% plasma - citrate samples of various species, interpolating the protein concentrations from the human standard curve, and expressing the interpolated concentrations as a percentage of the protein concentration in human plasma - citrate assayed at the same dilution. Reactive species: Bovine, Primate. Reactivity < 3% was determined for the following species: Mouse, Rat -
说明
Insulin-like growth factor I (IGF1) is a 70 amino acid hormone that this proteolytically processed from a larger precursor protein. IGF1 is structurally similar to insulin and has growth promoting effects.

功能
The insulin-like growth factors, isolated from plasma, are structurally and functionally related to insulin but have a much higher growth-promoting activity. May be a physiological regulator of [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblasts. Stimulates glucose transport in rat bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regard to enhancing glucose uptake. -
疾病相关
Defects in IGF1 are the cause of insulin-like growth factor I deficiency (IGF1 deficiency) [MIM:608747]. IGF1 deficiency is an autosomal recessive disorder characterized by growth retardation, sensorineural deafness and mental retardation. -

Interpolated concentration of native IGF1 was measured in duplicate at different sample concentrations in 96-well vs. 384-well plates. Undiluted samples are 2.5% serum. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). Sample dilutions are made in Sample Diluent NS + 1X Enhancer.

The concentrations of IGF1 were measured in duplicates, interpolated from the IGF1 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 2.5%, plasma (citrate) 1.25%, plasma (EDTA) 1.25%, and plasma (heparin) 1.25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IGF1 concentration was determined to be 99.58 ng/mL in serum, 121.23 pg/mL in plasma (citrate), 103.65 ng/mL in plasma (EDTA), and 110.43 ng/mL in plasma (heparin).

Linearity of dilution is determined based on interpolated values from the standard curve. Linearity of dilution defines a sample concentration interval in which interpolated target concentrations are directly proportional to sample dilution.
