Mouse haptoglobin ELISA KIT Cat. No. 6250 DILUTION OF SAMPLES
Samples containing more than 125 ng/ml HAPTOGLOBIN should be
further diluted and re-tested. The results obtained should be multiplied

CALCULATION OF RESULTS
Calculate the mean absorbance for each duplicate. Draw the standard

curve on semi-log graph paper by plotting net absorbance values of
standards against appropriate HAPTOGLOBIN concentrations. Read off
the HAPTOGLOBIN concentrations of the control and patient samples.
Multiply the values by the dilution factor of the samples. If samples were
diluted 1:20K then the values must be multiplied by 20,000 and results
PERFORMANCE CHARACTERISTICS Detection Limit: The minimum HAPTOGLOBIN concentration
detectable using this assay is below 1 ng/ml. The detection limit is
defined as the value deviating by 2 SD from the zero standard.

SPECIMEN COLLECTION AND HANDLING
Col ect blood by venipuncture, al ow clotting, and separating the serum by
centrifugation at room temperature. Do not heat inactivate the serum. If sera
can not be immediately assayed , store frozen for up to six months. Avoid
repeated freezing and thawing of samples. It is also possible to use plasma for
REAGENT PREPARATION
1. Dilute the Sample Diluent 1:10 with water (10 ml diluent in 90ml water).
Dilute only the required reagent. Store diluted solution at 2-8o C for 3-4
2. Dilute Wash Buffer (10x stock). Dilute the entire 60 ml with distil ed or
deionized water to 540 ml water (total volume 600 ml). Store at room
temperature for the entire use of the kit.
