HARDY DIAGNOSTICS DR900A NA

MRSA-Screen consists of latex reagent sensitized with a monoclonal antibody against penici lin—binding protein 2'(2a). or PBP2' (PBP2a), together with control latex and 2'extraction reagents to rapidly extract PBP2' from the bacterial cell membranes of MRSA. Extracts are prepared by boiling a suspension of S. aureus cells under alkaline conditions, followed by neutralization and a centrifugation step. The supernatant is subsequently mixed with the latexreagents on a test card and visible clumping or agglutination within three minutes with the sensitized latex but not the control latex confirms the presence of MRSA.MATERIALS SUPPLIEDSensitized Test Latex - (dropper bottle with pink cap) Latex particles are sensitized with a monoclonal antibody against PBP2'.Control Latex - (dropper bottle with a blue cap) Latex particles are sensitized with a monoclonal antibody of the same IgG subclass but against a human protein showing no reactivity with proteins of Staphylococcus aureus .Extraction Reagent 1 - (green cap) 0.1 mol/L NaOHExtraction Reagent 2 - (yellow cap) 0.5 mol/L KH 2 PO 4Test CardsMixing SticksPackage Insert
