An indirect ELISA using SeraCare's KPL anti-Group B Streptococcus antibody to detect various gram positive and gram negative bacteria. Samples were coated on the plate at a 1:100 dilution. Primary antibody was used at 1 ng/mL and HRP rabbit anti-goat secondary antibody was used at 62.5 ng/mL. ABTS was used as substrate, and the plate was read at 405 nm once color had developed appropriately.
