A cherniluminescent assay for hepatitis-B surface antigen is described which used an isoluminol derivative as the label. The assay is precise intra-assay CV, 1.96-2.45%; inter-assay CV, 5 2 6 8 . 1 1 % and has a lower detection limit for hepatitis-B surface antigen of 1.3 UA.

Abstract
Two commercial assay kits for detecting antibody to hepatitis A virus (antiβHAV) have been modified in order to increase their sensitivity. These modifications are made by less dilution of the test serum, in the case of Abbott HAVABβM assay, or by an increase in the volumetric ratio of the test serum to the labeled antiβHAV in the case of the Abbott HAVAB assay. These modifications result in 5β to 20βfold increases in test sensitivity and enable the detection of antiβHAV at 2β3 weeks following vaccination. The earlier detection of antiβHAV is important to vaccine development in assuring the presence of antibody levels in travelers sooner after vaccination.

Allantoin is separated by thin-layer chromatography (TLC) and sprayed with an acidic solution ofp-dimethylaminobenzaldehyde. The yellow color produced is read in a densitometer and compared with that of a standard. The lower limit of quantitation is 0.1 ~g per spot (0.5 mg/100 ml). The method can be
Few data are available to evaluate the performance of existing assays for antibody to the hepatitis E virus (anti-HEV). A panel of 164 randomized and coded sera was tested for anti-HEV by 12 different assays. The panel included a dilution series of an early convalescent human serum, known-positive s
A method is described for the assay of histone methyltransferase using soluble histones as substrate. The precipitation of the methylated protein on chromatography paper allows for greater sensitivity and more rapid sample processing than have previously been reported. After incubation of the enzyme
