Overview

Product name:	Human Anti-ALB(Anti-Albumin Antibody) ELISA Kit
Reactivity:	Human
Alternative Names:	Serum albumin Ab
Assay Type:	Competitive Inhibition
Sensitivity:	1.3 ng/mL
Standard:	200 ng/mL
Detection Range:	3.13-200 ng/mL
Sample type:	Serum, plasma and other biological fluids.
Assay length:	2.5h
Research Area:	Tumor immunity;Infection immunity;Hematology;Hepatology;Nutrition metabolism;
Test principle:	This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human Anti-ALB. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human Anti-ALB. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. 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 Human Anti-ALB in the samples is then determined by comparing the OD of the samples to the standard curve.

精密度

Intra-assay Precision (Precision within an assay)：CV%<8%

Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-assay Precision (Precision between assays)：CV%<10%

Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.

回收率

Matrices listed below were spiked with certain level of recombinant Anti-ALB and the recovery rates were calculated by comparing the measured value to the expected amount of Anti-ALB in samples.

Matrix	Recovery range	Average
serum(n=5)	83-95%	89%
EDTA plasma(n=5)	80-92%	86%
Heparin plasma(n=5)	85-97%	91%

线性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Anti-ALB and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
