The 48-base-long primordial building block of immunoglobulin light-chain variable regions is complementary to the primordial building block of heavy-chain variable regions.

The ancestral gene for immunoglobulin light-chain variable regions (Ig VLs) of the kappa as well as the lambda class apparently arose from about 12 tandem repeats of the 48-base-long primordial building block sequence TCT-TGC-GCA-GTA-AGT-CCA-CTC-CAG-GTC-ATA-TCC-AGT-CAG-GCT-GCT-GAA. Even today, amino acid residues 67 to 82 of each Ig V kappa L are still specified by a direct descendant in toto o...

Identification of the 48-base-long primordial building block sequence of mouse immunoglobulin variable region genes.

Mouse immunoglobulin heavy-chain variable region (Ig VH) genes apparently arose from the approximately 600-base-pair-long (approximately 12 tandem repeats of the 48-base-pair-long primordial building block sequence TTC-AGC-AGC-CTG-ACT-GGA-TAT-GAC-CTG-GAG-TGG-ACT-TAC-TGC-GCA-AGA) that in the original reading frame specified the amino acid sequence Phe-Ser-Ser-Leu-Thr-Gly-Tyr-Asp-Leu-Glu-Trp-Thr-...

Immunoglobulin heavy chain constant regions regulate immunity and tolerance to idiotypes of antibody variable regions.

Particular syngeneic adjuvant-free monoclonal antibodies are immunogenic and elicit antibody responses against the variable region idiotypes (Ids). We here study how heavy-chain constant regions (C(H)) regulate immune responses to Ids of free, uncomplexed monoclonal antibodies. To this end, we selected two hybridomas, called Id(3) and Id(A.01), that produce immunogenic IgM(lambda)2 directed tow...

Developmental progression of equine immunoglobulin heavy chain variable region diversity.

Humoral immunity is a critical component of the immune system that is established during fetal life and expands upon exposure to pathogens. The extensive humoral immune response repertoire is generated in large part via immunoglobulin (Ig) heavy chain variable region diversity. The horse is a useful model to study the development of humoral diversity because the placenta does not transfer mater...

Nested polymerase chain reaction amplification and sequencing analysis of the light-chain and heavy-chain variable regions in the influenza A H1N1 virus hemagglutinin monoclonal antibody gene.

The nested polymerase chain reaction (PCR) method was used for the amplification of the influenza A H1N1 virus hemagglutinin monoclonal antibody light-chain and heavy-chain genes. Sequence analysis of the obtained genes was then used to identify common cloning methods of the mouse immunoglobulin-kappa (Igκ) light-chain and heavy-chain variable gene regions. Twenty-two pairs of amplification pri...
