Syntaxin-4, Bio-Techne, MAB7894

Our team has carried out deep research in the published scientific literature to identify papers and reports using antibodies directed against human Syntaxin-4 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 9 commercial research antibodies against human Syntaxin-4 encoded by STX4.

The collection of antibodies was tested using HAP1 WT and STX4 KO cells in the applications WB (WT and KO cell lysates/60 µg protein), IP (WT cell lysate) and IF (WT and KO cells) according to YCharOS standard protocols (see reference).

In WB (1:2000 ab dilution) MAB7894 detected a band of appr. 34 kDa in WT cell lysate with no corresponding band observed 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 (10% of starting material). A faint band was also detected in immunodepleted extract (10% of total unbound fraction), showing that the antibody does not completely deplete the antigen from cell lysate. In IF (1:100 ab dilution), comparable staining intensities was observed in both KO and WT cells.
