5′ skewed Jα usage in RYIIRAG1 −/− and RYIIRAG2 −/− mice. (A) Percentage of TCRα mRNAs using Jαs found within the indicated 10-kb intervals in the Jα locus. The results represent 68 RYIIRAG1 −/− and 24 wild-type (WT) clones from the thymus, and 33 RYIIRAG1 −/− and 36 WT clones from the spleen. Schematic representation of the Jα locus is shown and position of Jαs from GenBank/EMBL/DDBJ accession no. M64239 with distances in kbs, the position of the PCR primers and probes used in B is shown. (B) V-Jα rearrangement measured by PCR on genomic DNA from total thymus. RAG1 −/− mouse tail DNA was used as a negative control. The first lane in each case represents ∼60 ng of template DNA diluted as shown. PCR on CD14 was used as loading control. Results are representative of two separate experiments with individual mouse samples.
