Sequestosome-1, Bio-Techne, MAB8028R

Our team has carried out deep research in the published scientific literature to identify papers and reports using antibodies directed against human Sequestosome-1 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 17 commercial research antibodies against human Sequestosome-1 encoded by SQSTM1.

The collection of antibodies was tested using U2OS WT and SQSTM1 KO cells in the applications WB (WT and KO cell lysates/25 µg protein), IP (WT cell lysate) and IF (WT and KO cells) according to YCharOS standard protocols (see reference).

In WB (1:1000 ab dilution) MAB8028R detected multiple bands. A band of appr. 60 kDa was specific to WT cell lysate not observed in KO cell lysate. A band was detected following IP (1 µg Ab used), this band was markedly more intense compared to band in input extract (10% of starting material) and no band was detected in immunodepleted extract (10% of total unbound fraction), showing that the antibody does completely deplete the antigen from cell lysate. In IF (1:500 ab dilution), clear staining was observed in WT cells, whereas KO cells showed no staining.
