Human Lipophilin B, Prostatein Like (LIPB) ELISA Kit

Principle of the Assay

The microtiter plate provided in this kit has been pre-coated with an antibody specific to LIPB. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to LIPB. 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 LIPB, 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 LIPB in the samples is then determined by comparing the O.D. of the samples to the standard curve.

For use with: Serum, Plasma, Tissue homogenates, and Other biological fluids.

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

Target Information

May bind androgens and other steroids, may also bind estramustine, a chemotherapeutic agent used for prostate cancer. May be under transcriptional regulation of steroid hormones.

Performance Characteristics

REPEATABILITY	Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level LIPB were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle, and high-level LIPB 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 0.125ng/mL.
ASSAY RANGE	0.312–20ng/mL
SPECIFICITY	This assay has high sensitivity and excellent specificity for the detection of LIPB. No significant cross-reactivity or interference between LIPB and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between LIPB and all analogs, therefore, cross reactivity may still exist.
