MAPK 1, GeneTex, GTX134457

Our team has carried out deep research in the published scientific literature to identify papers and reports using antibodies directed against human Mitogen-activated protein kinase 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 14 commercial research antibodies against human Mitogen-activated protein kinase 1 encoded by MAPK1.

The collection of antibodies was tested using HeLa WT and MAPK1 KO cells in the applications WB (WT and KO cell lysates/30 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) GTX134457 detected a band of appr. 40 kDa in WT cell lysate with no corresponding band observed in KO cell lysate. A faint band of higher molecular weight was observed in KO cell lysate. Only a band corresponding to the heavy chain was detected following IP (2 µg Ab used). In IF (1:200 Ab dilution), comparable staining intensity was observed in both KO and WT cells.

We highly encourage other scientists to share their observations.
