RNA-binding protein FUS, Abcam, ab243880

Our team has carried out an in-depth review of the published scientific literature to identify papers and reports using antibodies directed against the human RNA-binding protein Fused-in-Sarcoma, followed by extraction and evaluation of the available data to assess performance according to the pAbmAbs rating criteria.

YCharOS is conducting a large head-to-head study comparing 18 commercially available research antibodies against the human RNA-binding protein Fused-in-Sarcoma encoded by FUS.

The collection of antibodies was tested using HeLa WT and FUS KO cells in the applications WB (WT and KO cell lysates, 30 µg protein), IP (WT cell lysate), IF (WT and KO cells), and flow cytometry (WT and KO cells). Some antibodies were evaluated across multiple applications, whereas others were tested exclusively by flow cytometry, all according to YCharOS standard protocols (see reference).

In WB (1:1000 Ab dilution) ab243880 detected a band of appr. 70 kDa in WT cell lysate not observed in KO cell lysate. Only a weak band was detected following IP (1 µg Ab used). In IF (1:500 Ab dilution), a clear intense staining was observed in WT cells with no background staining in KO cells.

We highly encourage other scientists to share their observations.
