TDP-43, Proteintech, 10782-2-AP

Our team has carried out deep research in the published scientific literature to identify papers and reports using antibodies directed against human TCP-43 and followed up by extraction and evaluation of the available data to assess its performance according to pAbmAbs rating criteria.

YCharOS is here conducting a large head-to-head study comparing 18 commercial research antibodies against human TDP-43 encoded by TARDBP

The collection of antibodies was tested using HAP1 WT and TARDBP KO cells in the applications WB (WT and KO cell lysates/50 µg protein), IP (WT cell lysate) and IF (WT and KO cells) according to YCharOS standard protocols (see reference).

In WB (1:5000 ab dilution) 10782-2-AP detected a band of appr. 45 kDa in WT cell lysate along with a faint band of lower molecular weight. No bands were detected in KO cell lysate. A band was detected following IP (2 µg Ab used), this band was more intense compared to band in input extract (4% of starting material). A faint band was also detected in immunodepleted extract (4% of total unbound fraction), showing that the antibody does not completely deplete the antigen from cell lysate. In IF (1:400 ab dilution) a clear stain of WT cells was observed compared to KO cells showing some background.

We highly encourage other scientists to share their observations.
