title: Allelic inclusion in the pre-B-cell line 18-81.
abstract: In an Abelson-virus-transformed mouse lymphoid cell line with pre-B-cell characteristics, a few cells continuously produce heavy chains from both homologs. Each chain has a different variable region. These cells thereby exhibit allelic inclusion rather than allelic exclusion.
