A sandwich enzyme-linked immunosorbent assay for human plasma apolipoprotein A-V concentration.
Apolipoprotein A-V (apoA-V) is a recently discovered apolipoprotein that appears to have a role in plasma triglyceride (TG) transport. We have developed an ELISA for apoA-V using monoclonal antibodies that has a lower limit of detection of 0.3 ng/ml and linearity up to 20 ng/ml. The ELISA was then used to quantify plasma apoA-V in 196 healthy subjects and 106 patients with insulin-resistant dia...
متن کاملEnzyme-linked immunosorbent assay for human plasma apolipoprotein B.
A noncompetitive enzyme-linked immunosorbent assay (ELISA) has been developed for measuring total plasma apolipoprotein (apo) B using affinity purified polyclonal and monoclonal antibodies. Microtiter plates from different manufacturers were tested with regard to their IgG binding characteristics; only one plate yielded consistent coefficients of variation of less than 5%. The optimal plasma di...
متن کاملApplication of a modified human enzyme-linked immunosorbent assay kit for diagnosis of hydatidosis in sheep
Cystic hydatid disease (hydatidosis) is one of the most important zoonosis that is caused by the larval stage of Echinococcus granulosus . As its diagnosis by clinical symptoms alone is difficult and confusing, serologic diagnostic techniques are used to confirm the disease. These techniques can also be used for epidemiologic studies. The present study was performed with a commercial human en...
متن کاملQuantification of human apolipoprotein A-IV by "sandwich"-type enzyme-linked immunosorbent assay.
A specific and sensitive "sandwich"-type enzyme-linked immunosorbent assay (ELISA) has been developed for quantifying human apo A-IV. Using apo A-IV immunosorbent columns, we isolated monospecific anti-apo A-IV antibodies for coating the ELISA plates and for preparing peroxidase-antibody conjugate. The assay can detect as little as 0.20 ng of apo A-IV, with mean intra- and interassay CVs of 3.6...
متن کاملQuantitation of apolipoprotein A-IV in human plasma using a competitive enzyme-linked immunosorbent assay.
A method for measuring human apolipoprotein A-IV has been developed using the competitive enzyme-linked immunosorbent assay (ELISA) system. The assay described is relatively easy, rapid, and inexpensive to perform, uses convenient dilutions of plasma (1/8-1/32) but is sensitive enough to quantitate the apoA-IV content of lipoproteins following gel filtration of small (0.3-0.5 ml) volumes of pla...
