Attack on the clones? Human FOXP3 detection by PCH101, 236A/E7, 206D, and 259D reveals 259D as the outlier with lower sensitivity
Open accessAbstract
To the editor: We read with great interest the report by Tran and colleagues in which the authors studied the induction of FOXP3 in naive human T cells.[1][1] The authors state that, in the absence of exogenous TGF-β, only a minor subset of activated human T cells express FOXP3. In contrast,

There is a general consensus that the 236A/E7 and 259D anti-human FOXP3 Ab clones are optimal.
“Several studies have compared different anti-human FOXP3 Ab clones, and although there is some debate, there is a general consensus that the 236A/E7 and 259D clones are optimal [394-398].”
From Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition) (2021) · cites this paper as [398]
In the letter’s comparison of antibody clones (pp. 463–464), 236A/E7 performs similarly to PCH101 and 206D, but 259D misses FOXP3 expression detected by the other clones. The authors explicitly call 259D an outlier and a less sensitive detector, contrary to describing it as optimal. (LLM, conf=0.93)

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.
