Transgenic mammals having human Ig loci including plural VH and Vkappa regions and
antibodies produced therefrom |
(57) The present invention relates to transgenic non-human animals that are engineered
to contain human immunoglobulin gene loci. In particular, animals in accordance with
the invention possess human Ig loci that includes plural variable (VH and V kappa
) gene regions. Advantageously, the inclusion of plural variable region genes enhances
the specificity and diversity of human antibodies produced by the animal. Further,
the inclusion of such regions enhances and reconstitutes B-cell development to the
animals, such that the animals possess abundant mature B-cells secreting extremely
high affinity antibodies.
