Lipoteichoic acid (LTA) is a major constituent of the cell wall of gram-positive bacteria. These organisms have an inner (or cytoplasmic) membrane and, external to it, a thick (up to 80 nanometer) peptidoglycan layer. The structure of LTA varies between the different species of Gram-positive bacteria and may contain long chains of ribitol or glycerol phosphate. LTA is anchored to the cell membrane via a diacylglycerol. It acts as regulator of autolytic wall enzymes (muramidases). It has antigenic properties being able to stimulate specific immune response.

Balb / c female mice are immuned by lipoteichoic acid antigens extracted from cell walls of the staphylococcus aureus, then monoclonal antibodies L are obtained and are IgG immune globulin after being detected, and the valence of the antibodies is 1*106. The monoclonal antibodies are purified by a saturated ammonium sulfate precipitation and affinity chromatography technology. Lipoteichoic acids serve as coating antigens, the obtained monoclonal antibodies serve as enzyme-labeled antibodies, and then a competition-method ELISA kit is manufactured and is used for diagnosing staphylococcus aureus infection which serves as one of references for clinical diagnosis.
