Whole IgG antibodies are isolated as intact molecules from antisera by immunoaffinity chromatography. They have an Fc portion and two antigen binding Fab portions joined together by disulfide bonds and therefore they are divalent. The average molecular weight is reported to be about 160 kDa. The whole IgG form of antibodies is suitable for the majority of immunodetection procedures and is the most cost effective.
Storage: Store at 2-8°C. Prepare working dilution on day of use.
Expiration date: one year from date of receipt. The expiration date may be extended if test results are acceptable for the intended use.
Colloidal gold conjugates are widely used commercially in lateral flow immunoassays due to their ease of production, conjugate stability and intense optical properties that generate highly sensitive tests with results visible to the naked eye. Conjugates are prepared by passive absorption of the antibody to the gold particle, and are sterile filtered in a low ionic strength buffer containing a preservative.
