TY - JOUR T1 - The production and testing of staphylococci with clumping factor activity for use in the assay of fibrinogen degradation products JF - Journal of Clinical Pathology JO - J Clin Pathol SP - 377 LP - 380 DO - 10.1136/jcp.26.5.377 VL - 26 IS - 5 AU - G. Richardson Y1 - 1973/05/01 UR - http://jcp.bmj.com/content/26/5/377.abstract N2 - A method for the large-scale production of a staphylococcal preparation for use in the assay of fibrinogen degradation products is described. The material is assayed against a fibrinogen standard and is shown to be stable over long periods and of high sensitivity. The possibility of production on an occasional basis in a routine laboratory is discussed. ER -
