One gamma heavy chain and 10 kappa light chain cynomolgus monkey (Macaca fascicularis) immunoglobulin cDNAs have been cloned and sequenced. Comparisons of the variable (V) regions to human antibody sequences have revealed extensive identity, exhibiting 93% at the amino acid level for the VH framework regions, and 88-99% for the V kappa frameworks.(More)
The human papillomavirus (HPV) E1 and E2 proteins bind cooperatively to the viral origin of replication (ori), forming an E1-E2-ori complex that is essential for initiation of DNA replication. All other replication proteins, including DNA polymerase alpha-primase (polalpha-primase), are derived from the host cell. We have carried out a detailed analysis of(More)
Multiple myeloma is a malignancy of plasma cells for which there is no effective treatment. To develop an immunotherapeutic agent, we have raised a high affinity mAb (AT13/5) against CD38, one of the few well-characterized surface Ags present on myeloma cells. Since murine monoclonals have many disadvantages as human therapeutics, we prepared two engineered(More)

The complete nucleotide sequence of the gene for the 230-kDa precursor to the major merozoite surface antigens (PMMSA) of Plasmodium yoelii YM has been determined. A single open reading frame of 5316 bp encodes a protein of calculated molecular mass 197,000. The deduced amino acid sequence contains potential signal peptide and membrane anchor sequences of(More)
We have analyzed human donor DNA for the presence of sequences corresponding to allelic variants of the IFN-alpha 2 locus. Using both restriction enzyme digestion of PCR-amplified fragments and sequence analysis of these fragments, we have identified the three reported allelic variants, IFN-alpha 2a, IFN-alpha 2b, and IFN-alpha 2c, in genomic DNA derived(More)
A human anti-hepatitis A virus mAb was rescued from a hybridoma cell line by conventional cDNA cloning, and expressed in CHO cells. The full nucleotide sequences of the mAb H and L chains were determined, revealing a VHI/V lambda II V region combination. Comparisons with germline V genes suggest that the V regions had undergone somatic mutations(More)
Human monoclonal antibody production has been hampered for many years by the instability of cell lines and low levels of expression of the antibodies. We describe here the rescue of human immunoglobulin genes utilizing micro-mRNA preparation from a small number of human hybridoma cells and conventional cDNA cloning. This allows cloning and immediate(More)
Polymerase chain reaction (PCR) methodology (1) has become a routine method for selectively amplifying segments of DNA from a wide variety of sources. Amplification of specific sequences is dependent upon an exact match between the template DNA and the oligonucleotide primers. Mismatches at the 3' terminus lead to greatly reduced amplification, with no(More)
Sixteen Chinese chronic hepatitis B virus (HBV)-infected patients were treated with recombinant interferon-alpha 2a (rIFN-alpha 2a). Of these, 8 made a response to IFN, with titers of neutralizing antibody of 141-4525 as determined by an antiviral neutralization bioassay. To determine whether the immunogenicity of the IFN was directly linked to the(More)
