Preparation of Laboratory Kit for Lipoteichoic acid as One of the Constituents of Gram-Positive Bacterial Cell Wall

Abstract

The study includes the production of antibody for LTA in the rabbit after isolation and purefication from S.aureus and St.viridans by injecting the animals regullary and consecutively with pure LTA. Kit was prepared to investigate the presence of antibodies in sera of injected animals by ELISA, the absorbance of the test samples for each of S.aureus - LTA and St.viridans - LTA were 1.0700 ± 0.0141 and 1.0100 ± 0.0141 respectively, The absorbance of control sample, which represent sera of lab animals injected with distilled water was 0.9300 ± 0.0141.
