The reagent can be used in the following method to detect antibodies in a sample which involvesa. contacting the sample with protein A linked to a solid support,b. incubating the sample-protein A linked to the solid support,c. washing the incubated sample-protein A linked to the solid support,d. contacting the washed sample-protein A with the reagent,e. incubating the sample-protein A and reagent,f. washing the incubated sample-protein A-reagent, andg. determining the enzymatic activity of the resultant mass.
摘要:
A hepatitis B vaccine containing a peptide with an amino acid chain of at least six consecutive amino acids within the pre-S gene coded region of the envelope of hepatitis B virus. The vaccine being free of an amino acid sequence corresponding to the naturally occurring envelope proteins of hepatitis B virus and a physiologically acceptable diluent. The peptide being free or linked to a carrier. The carrier being a conventional carrier or a novel carrier including a lipid vesicle stabilized by cross-linking and having covalently bonded active sites on the outer surface thereon. Such novel carrier being useful not only to link the novel peptide containing an amino acid chain with amino acids within the pre-S gene coded region of the surface antigen or hepatitis B virus, but can also be used to bind synthetic peptide analogues of other viral proteins, as well as bacterial, allergen and parasitic proteins of man and animals. The peptides of the invention can be utilized in diagnostics for the detection of antigens and antibodies.

摘要:
Virus-containing media are treated and the viruses broken down into sub-units by mixing with trialkyl phosphates in the presence of a wetting agent. In comparison with conventional means, sub-unit vaccines prepared therefrom have low toxic pyrogen content, and influenza viruses of Types A and B are disrupted without substantial decreases in neuraminidase level. The method can be used on viruses contained in relatively dilute allantoic fluids as well as those in concentrated centrifugates.
