1 sensitivity: minimum detection concentration is less than 1 standard. Linearity of dilution. Sample linear regression and the expected concentration correlation coefficient R value is 0.990.
2: no specific reaction with other cytokines.
3 repeatability: plate, plate between the coefficients of variation were less than 10%.
Human type III procollagen amino terminal peptide ELISA kit steps:
1 before use, all reagents and mixing. Do not allow liquid to produce a large number of bubbles, so as to avoid adding a large number of bubbles, resulting in the addition of the error.
2 according to determine the number of sample number plus standard strip number. Each standard and blank hole is recommended to do the hole. Each sample can be made according to its own quantity, and can be used as a hole in the hole.
3 diluted after standard 50ul in reaction hole, added to the sample 50 UL in reaction hole to be measured. Immediately joined the 50 UL antibody biotin. Cover the membrane plate, gently oscillating mixing, 37 degrees Celsius for 45 minutes.
4 left hole liquid, each hole filled with washing liquid, oscillating 30 seconds off the washing liquid, pat dry with absorbent paper. Repeat this operation 4 times. If the washing machine with washing, washing times increased once.
6 left hole liquid, each hole filled with washing liquid, oscillating 30 seconds off the washing liquid, pat dry with absorbent paper. Repeat this operation 4 times. If the washing machine with washing, washing times increased once.
7 per hole adding substrate A, B 50ul, gently oscillating mixing, 37 degrees 5 minutes incubation. Avoid light.
8 remove ELISA plate, quickly add 50ul terminated liquid, adding the stop solution immediately after the determination results.
9 od determination of each hole at the wavelength of 450nm.
The result of judgment and analysis:
1, instrument value: Yu Bo 450nm ELISA od read the hole on the instrument
2, to the OD value as a vertical coordinate (y), corresponding ot standard concentrations as a horizontal coordinate (x), do have corresponding curve, sample ot content can be according to the OD value by standard curve conversion out corresponding concentration, multiplied by the dilution multiple; or with the standard concentration and the OD value calculated the regression equation of the standard curve, the sample OD value in the equation to calculate the sample concentration, multiplied by the dilution factor is the actual concentration of the sample.
