TLDR
The first report of the physical linkage of the variable and constant loci of a human Ig gene family is provided by demonstrating that the most proximal known human VH segments lie within 100 kb of the constant region locus.Abstract:
We present a detailed analysis of the content and organization of the human immunoglobulin VH locus. Human VH genes representing five distinct families were isolated, including novel members belonging to two out of three of the known VH gene families (VH1 and VH3) as well as members of three new families (VH4, VH5, and VH6). We report the nucleotide sequence of 21 novel human VH genes, many of which belong to the three new VH gene families. In addition, we provide a preliminary analysis of the organization of these gene segments over the full extent of the locus. We find that the five multi-segment families (VH1-5) have members interspersed over nearly the full 1500-2000 kb of the VH locus, and estimate that the entire heavy chain locus covers 2500 kb or less. Finally, we provide the first report of the physical linkage of the variable and constant loci of a human Ig gene family by demonstrating that the most proximal known human VH segments lie within 100 kb of the constant region locus.read more

TL;DR: Early Ig transcripts from human fetal tissues are identified, revealing a discrete expression pattern of V genes as compared with the adult repertoire, and heavy chain transcripts have been obtained, providing evidence for the occurrence of an early switch mechanism in ontogeny.

Amino acid sequence of the variable domains of a human anti-Rh(c) antibody: Presence of an unusually long CDR3 in the λ chain
TL;DR: The complete amino acid sequence of the lambda light chain and the variable domain of the heavy chain of an anti-Rh(c) human monoclonal antibody were determined and it is indicated that this lambda chain may be assigned to the variable region subgroup I.

Selected antibodies binding to anionic phospholipids and aminophospholipids and their use in treatment
TL;DR: In this article, the authors describe antibody compositions and uses of such antibodies in the treatment of diseases such as cancer, in which the antibodies are observed to bind to a phosphatidylserine (PS)-coated ELISA plate in an ELISA conducted in the presence of 10%.

TL;DR: Southern blot analysis demonstrated that a high proportion of mink VH genes is VHIII related, and according to Southern blot analysis there may be 5–7 Cγ genes at the mink IgH locus.
