13. Specifity of DNA-basic polypeptide interactions. Influence of neutral residues incorporated into polylysine and polyarginine.
An approach is described for evaluation of the specificity of basic polypeptides concerning the base pair composition of DNA. The polypeptides were covalently bound to CNBr activated agarose and two DNAs strongly different in base composition but of equal molecular weight were loaded and detached by a NaCl gradient. The difference in the NaCl concerntrations

14. Initial Interaction of Rotavirus Strains with N-Acetylneuraminic (Sialic) Acid Residues on the Cell Surface Correlates with VP4 Genotype, Not Species of Origin
We examined 41 human and animal rotavirus strains representative of all known P genotypes for their dependency on cellular N-acetylneuraminic (sialic) acid (SA) residues for infectivity. Our results showed that all rotaviruses studied, whether of animal or human origin, belonging to P genotypes [1], [2], [3], and [7] depended on SA residues on the cell surfa

15. Organization of the left-hand end of the herpes simplex virus type 2 BglII N fragment.
We have determined the complete nucleotide sequence surrounding the region coding for a 38,000-dalton protein of herpes simplex virus type 2 strain 333 that is encoded between map coordinates 0.58 to 0.595 on the viral genome. The sequence data have revealed an open translational reading frame of 1,011 nucleotides encoding a protein of 337 amino acids. Upstr

16. Detection of immunoglobulin M and G antibodies against cytomegalovirus early and late antigens by enzyme-linked immunosorbent assay.
A sensitive and reproducible enzyme-linked immunosorbent assay (ELISA) is described for the detection of immunoglobulin M and antibodies with specifity for human cytomegalovirus (CMV) early (CMV-EA) and late (CMV-LA) antigens. The emphasis is on the production of high-quality CMV antigens, CMV-EA and CMV-LA separately, and conditions for their application in

17. Evidence for cobinding of self- and allopeptides to human class II major histocompatibility antigen DR1 by energy transfer.
Purified human class II major histocompatibility antigen HLA-DR1 was subjected to high-performance gel filtration with fluorescence detection to investigate simultaneous binding of two classes of peptides: the N-terminally fluoresceinated allopeptides fluorescein isothiocyanate (FITC)-conjugated DR1 beta-(66-78) and FITC-conjugated DR3 beta-(66-78), derived
