This assay has high sensitivity and excellent specificity for detection of Apolipoprotein A1 (APOA1). No significant cross-reactivity or interference between Apolipoprotein A1 (APOA1) and analogues was observed.

For unopened kit: All the reagents should be kept according to the labels on vials. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20 degree C upon receipt while the others should be at 4 degree C. For opened kit: When the kit is opened, the remaining reagents still need to be stored according to the above storage condition. Besides, please return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal. The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Samples: Serum, plasma, tissue homogenates, Cell lysates, cell culture supernates and other biological fluids. Assay Type: Sandwich. Detection Range: 6.25-400ng/mL. Sensitivity: Typically less than 2.35ng/mL.

Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Apolipoprotein A1 (APOA1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Apolipoprotein A1 (APOA1) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 . Intra-Assay: CV<10% . Inter-Assay: CV<12% . Assay Procedure Summary: 1. Prepare all reagents, samples and standards;. 2. Add 100uL standard or sample to each well. Incubate 2 hours at 37 degree C;. 3. Aspirate and add 100uL prepared Detection Reagent A. Incubate 1 hour at 37 degree C;. 4. Aspirate and wash 3 times;. 5. Add 100uL prepared Detection Reagent B. Incubate 30 minutes at 37 degree C;. 6. Aspirate and wash 5 times;. 7. Add 90uL Substrate Solution. Incubate 15-25 minutes at 37 degree C;. 8. Add 50uL Stop Solution. Read at 450nm immediately.

Principle of the Assay: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Apolipoprotein A1 (APOA1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Apolipoprotein A1 (APOA1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Apolipoprotein A1 (APOA1), 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 Apolipoprotein A1 (APOA1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

This gene encodes apolipoprotein A-I, which is the major protein component of high density lipoprotein (HDL) in plasma. The protein promotes cholesterol efflux from tissues to the liver for excretion, and it is a cofactor for lecithin cholesterolacyltransferase (LCAT) which is responsible for the formation of most plasma cholesteryl esters. This gene is closely linked with two other apolipoprotein genes on chromosome 11. Defects in this gene are associated with HDL deficiencies, including Tangier disease, and with systemic non-neuropathic amyloidosis. [provided by RefSeq, Jul 2008]

APOA1: Participates in the reverse transport of cholesterol from tissues to the liver for excretion by promoting cholesterol efflux from tissues and by acting as a cofactor for the lecithin cholesterol acyltransferase (LCAT). As part of the SPAP complex, activates spermatozoa motility. Interacts with APOA1BP and CLU. Component of a sperm activating protein complex (SPAP), consisting of APOA1, an immunoglobulin heavy chain, an immunoglobulin light chain and albumin. Interacts with NDRG1. Major protein of plasma HDL, also found in chylomicrons. Synthesized in the liver and small intestine. The oxidized form at Met-110 and Met-136 is increased in individuals with increased risk for coronary artery disease, such as in carrier of the eNOSa/b genotype and exposure to cigarette smoking. It is also present in increased levels in aortic lesions relative to native ApoA-I and increased levels are seen with increasing severity of disease. Belongs to the apolipoprotein A1/A4/E family.
