Assay procedure
- Prepare all reagents before starting assay procedure. It is
recommended that all Standards and
Samples be added in duplicate to the Microelisa Stripplate.
- Add standard: Set Standard wells, testing sample wells. Add standard
50μl to standard well.
- Add Sample: Add testing sample 10μl then add Sample Diluent 40μl to
testing sample well;
- Add 50μl of HRP-conjugate reagent to each well, cover with an
adhesive strip and incubate for 60
minutes at 37°C.
- Aspirate each well and wash, repeating the process four times for a
total of five washes. Wash by
filling each well with Wash Solution (400μl) using a squirt bottle,
manifold dispenser or autowasher.
Complete removal of liquid at each step is essential to good
performance. After the last wash, remove any remaining Wash Solution by
aspirating or decanting. Invert the plate and blot it against clean
paper towels.
- Add chromogen solution A 50μl and chromogen solution B 50μl to each
well. Gently mix and incubate for 15 minutes at 37°C. Protect from
light.
- Add 50μl Stop Solution to each well. The color in the wells should
change from blue to yellow. If the color in the wells is green or the
color change does not appear uniform, gently tap the plate to ensure
thorough mixing.
- Read the Optical Density (O.D.) at 450 nm using a microtiter plate
reader within 15 minutes.
Calculation of results
- Calculate the mean absorbance value A450 for each set of reference
standards and samples.
- Divide the average A450 value for each standard, control and test
sample by the average A450 of standard0 and multiply by 100 to obtain
%B/B0 for each sample.
- Prepare a standard curve by plotting the average absorbance of each
standard versus the corresponding concentrations of the standards on
linear-log graph paper or the %B/B0 value for each standard versus the
corresponding concentration of the standard on linear-log or logit-log
graph paper. logit=ln(B/ B0)/(1-B/ B0)
- Any values obtained for diluted samples must be further converted by
applying the appropriate dilution factor in the calculations.
- The standard density is a X, the B/ B0 is a Y, sitting to mark the
paper in the logit- log up draw a standard curve. According to the B/ B0
that need to be measured the sample can from sit to mark the density
value that the paper looks up the sample up.
- The sensitivity by this assay is 5ng/mL
- The standard curve presented here is an example of the data
typically produced with this kit; however, your results will not be
identical to these.
- Standard curve match
