Generally, one references important products in the methods section of the report by describing the product, who makes it, and how it is used.
"Procedures
Base-line plasma samples from each woman with an event and each control subject were thawed and assayed for hs-CRP, serum amyloid A, and Lp(a) lipoprotein with use of latex-enhanced immunonephelometric assays on a BN II analyzer (Dade Behring, Newark, Del.). Apolipoprotein A-I and apolipoprotein B-100 were simultaneously measured with this device by immunoassay. Total cholesterol, HDL cholesterol, and directly obtained LDL cholesterol levels were measured on a Hitachi 911 analyzer (Roche Diagnostics, Indianapolis) with reagents from Roche Diagnostics and Genzyme (Cambridge, Mass.). Plasma levels of sICAM-1 and interleukin-6 were measured by enzyme-linked immunosorbent assay (R & D Systems, Minneapolis), and the total plasma homocysteine level was measured with an IMx homocysteine assay (Abbott Laboratories, Abbott Park, Ill.) as previously reported.16
