Abstract

CD28 (Tp44) is a human T-cell-specific homodimer surface protein that may participate in T-cell activation. We have isolated a cDNA clone encoding CD28 by a simple and highly efficient cloning strategy based on transient expression in COS cells. Central to this strategy is the use of an efficient method to prepare large plasmid cDNA libraries. The libraries are introduced into COS cells, where transient expression of surface antigen allows the isolation of cDNAs by way of monoclonal antibody binding. The CD28 cDNA encodes a highly glycosylated membrane protein with homology to the immunoglobulin superfamily and directs the production of a homodimer in transfected COS cells.

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.
