Abstract

Four mAb able to recognize transforming growth factor-beta 2 (TGF-beta)2 were obtained. One of these mAb, 1D11.16, was able to neutralize the biological activity of both TGF-beta 1 and beta 2 in vitro. This was demonstrated in an Il-1, PHA-dependent thymocyte mitogenic assay that is inhibitable by TGF-beta in a dose-dependent manner. All four mAb recognized the dimeric form of TGF-beta 2 in Western blots. The mAb were also found to immunoprecipitate [125I]-TGF-beta 2. mAb 3C7.14 coupled to Sepharose could efficiently immunoaffinity purify TGF-beta 2 from a complex mixture of proteins. Affinity constants were determined for the four mAb and they ranged from 3.4 x 108 to 1.6 x 107 L/mol.

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.
