Introduction | Pyridinoline cross-linked carboxyterminal telopeptide of type I collagen, ICTP, is the carboxyterminal telopeptide of type I collagen, joined through trivalent crosslinks and released during the degradation of mature type I collagen. Type I collagen is the most abundant collagen type in the body and the only collagen type found in the mineralized bone. It accounts for more than 90% of organic bone matrix. In addition, type I collagen is found in loose connective tissues together with other collagen types. |
Target | C-Telopeptide Of Type I Collagen (ICTP) |
Reactivity | Human |
Tested Applications | ELISA |
Recommended dilutions | Optimal dilutions/concentrations should be determined by the end user. |
Storage | Shipped at 4 °C. Upon receipt, store the kit according to the storage instruction in the kit's manual. |
Validity | The validity for this kit is 6 months. |
Stability | The stability of the kit is determined by the rate of activity loss. The loss rate is less than 5% within the expiration date under appropriate storage conditions. To minimize performance fluctuations, operation procedures and lab conditions should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same user throughout. |

Assay Principle | This kit is based on competitive enzyme-linked immuno-sorbent assay technology. An antibody is pre-coated onto a 96-well plate. Standards, test samples, and biotin-conjugated reagent are added to the wells and incubated. A competitive inhibition reaction takes place between the biotin-labelled ICTP and the unlabelled- ICTP on the pre-coated antibody. The HRP-conjugated reagent is then added, and the whole plate is incubated. Unbound conjugates are removed using wash buffer at each stage. TMB substrate is used to quantify the HRP enzymatic reaction. After TMB substrate is added, only wells that contain sufficient ICTP will produce a blue coloured product, which then changes to yellow after adding the acidic stop solution. The intensity of the color yellow is inversely proportional to the ICTP amount bound on the plate. The OD is measured spectrophotometrically at 450 nm in a microplate reader, from which the concentration of ICTP can be calculated. |

Results Calculation | This assay is competitive, therefore there is an inverse correlation between ICTP concentration in the sample and the absorbance measured. Create a graph with the log of the standard concentration (y-axis) and average absorbance measured (x-axis). Apply a best fit trendline through the standard points. The ICTP concentration of the samples can be interpolated from the standard curve. |

Note | This product is for research use only. The range and sensitivity is subject to change. Please contact us for the latest product information. For accurate results, sample concentrations must be diluted to mid-range of the kit. If you require a specific range, please contact us in advance or write your request in your order comments. Please note that our ELISA and CLIA kits are optimised for detection of native samples, rather than recombinant proteins. We are unable to guarantee detection of recombinant proteins, as they may have different sequences or tertiary structures to the native protein. |
