Human Hemoglobin Gamma 1 (HBg1) ELISA Kit

Principle of the Assay

The microtiter plate provided in this kit has been pre-coated with an antibody specific to HBg1. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to HBg1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain HBg1, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of HBg1 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

For use with: Serum, Plasma, and Erythrocyte lysates.

For Research Use Only. Not for use in diagnostic procedures.

Performance Characteristics

REPEATABILITY	Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level HBg1 were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle, and high-level HBg1 were tested on 3 different plates, with 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%
SENSITIVITY	The minimum detectable dose was 122.6ng/mL.
ASSAY RANGE	468–30,000ng/mL
SPECIFICITY	This assay has high sensitivity and excellent specificity for the detection of HBg1. No significant cross-reactivity or interference between HBg1 and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between HBg1 and all analogs, therefore, cross reactivity may still exist.
