Abstract

A method using PCR amplification and primer extension with fluorescent oligonucleotides was developed to analyze T-cell repertoires. The sizes of the hypervariable CDR3-like regions of the murine T-cell antigen receptor beta chains were measured for all possible V beta-J beta combinations. This analysis shows that beta chains are distributed into at least 2000 groups, a value that provides a lower limit to their complexity. The CDR3 sizes appear to be dependent on the J beta and especially the V beta segment used and correlates with amino acid sequence motifs in the corresponding CDR1 region. This feature of T-cell receptors is discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
