Abstract

We have isolated three cDNA clones for beta 2-microglobulin, the small subunit of the major histocompatibility antigens. beta 2-Microglobulin makes up less than 0.1% of mouse liver protein, and its mRNA is approximately 0.03% of liver poly(A)+ mRNA. The cDNA clones were identified by screening 1400 cDNA clones made from 9--10S mouse liver poly(A)+ mRNA. The procedure for screening the cDNA clones involved binding pooled plasmid DNA to nitrocellulose filters and testing the ability of each filter to select beta 2-microglobulin mRNA. The filter-selected mRNAs were assayed for their ability to direct the synthesis of beta 2-microglobulin in translation reactions in vitro. The isolated clones were shown by nucleotide sequence analysis to encode beta 2-microglobulin. The positive-selection--hybridization assay has been modified to facilitate the screening of large numbers of cDNA clones, and the modified assay should allow the isolation of cDNAs corresponding to any mRNA whose in vitro translation products can be immunoprecipitated. These modifications are of particular value in the isolation of cDNA clones corresponding to rare species of mRNA.

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.
