Abstract: There is now a market for kits containing the necessary components for performing protein synthesis reactions using template DNA of the experimenter. One category of existing system for performing protein synthesis reactions is based on an S-30 extract from the bacteria E. coli. It is disclosed here that a simple fractionation process can dramatically improve the performance of an S-30 prokaryotic protein synthesis reaction mixture. In one embodiment, the fractionation is a simple freezing and thawing of an S-30 extract combined with a supplemental mix, followed by centrifugation. The resulting fractionated S-30 reaction mixture yields more full-length target protein and less non-full length or non-target protein than possible using prior art S-30 systems.

Abstract: An antibody raised against an epitope of a peptide having an amino acid sequence selected from a group consisting of Leu Asp Gly Tyr Pro Ser Asp Tyr Asp Pro Phe Val Glu Asn Ala Gln Ile Tyr (SEQ ID NO:1) and Leu Asp Gly Tyr Pro Ser Asp Tyr Asp Pro Phe Glu Glu Asn Ala Gln Ile Tyr (SEQ ID NO:2) is advantageously used in an indirect immunoassay to detect the presence of active Human Herpesvirus-6 in a patient sample.

Abstract: A vector for the direct cloning of the products of PCR protocol incorporates single nucleotide overhangs at one or both ends of a linearized DNA segment. The single nucleotide overhangs are uracil or inosine residues, as desired, to facilitate cloning of the desired PCR products.

Abstract: An antibody raised against an epitope of a peptide having an amino acid sequence selected from a group consisting of LDGYPSDYDPFVENAQIY (SEQ ID NO:1) and LDGYPSDYDPFEENAQIY (SEQ ID NO:2) is advantageously used in an indirect immunoassay to detect the presence of active Human Herpesvirus-6 in a patient sample.

Abstract: A method for forming directionally clonable randomly primed cDNA molecules includes the step of priming first strand synthesis using a set of first strand cDNA primers having the sequence 5'-XXNNNNNN-3' where XX is a constant dinucleotide pair across the set and NNNNNN is a random hexanucleotide, the set including primers representing all random hexanucleotides.
