Cathepsin B, GeneTex, GTX134724

YCharOS previously conducted a large head-to-head study comparing commercial research antibodies against human Cathepsin B, encoded by CTSB. The antibodies were evaluated based on published scientific literature and experimental data according to the pAbmAbs rating criteria. In the previous study, this antibody was evaluated by YCharOS using HAP1 WT and CTSB KO cells in Western blot (WB), following YCharOS standard protocols (see reference). Building on these previous findings, the antibody was further evaluated by YCharOS in immunofluorescence (IF) using HAP1 WT and CTSB KO cells and in IP using HAP1 WT cell lysate. In IF, at an antibody dilution of 1:800, WT cells exhibited a more intense staining compared to KO cells with background staining observed. No putative band was detected following IP. We highly encourage other scientists to share their experience.

Our team has carried out deep research in the published scientific literature to identify papers and reports using antibodies directed against human Cathepsin B 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 13 commercial research antibodies against human Cathepsin B encoded by CTSB.

The collection of antibodies was tested using HAP1 WT and CTSB KO cells in the application WB (WT and KO cell lysates/30 µg protein), according to YCharOS standard protocols (see reference).

In WB (1:100 Ab dilution) GTX134724 detected a band of appr. 38 kDa in WT cell lysate with no corresponding band in KO cell lysate. Several bands of higher molecular weight were observed in both genotypes.

We highly encourage other scientists to share their observations.
