TRIM21, Thermo Fisher Scientific, MA5-51296

Our team has carried out deep research in the published scientific literature to identify papers and reports using antibodies directed against human The tripartite motif containing-21(TRIM21) 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 10 commercial research antibodies against human The tripartite motif containing-21encoded by the TRIM21 gene.

The collection of antibodies was tested using A549 WT and TRIM21 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) MA5-51296 detected a band of appr. 51 kDa in WT cell lysate with no corresponding band observed in KO cell lysate. Extracts from A549 WT, A549 TRIM21 KO, PANC-1, SU.86.86, H4, 5637, BxPC-3, A-172, U-87 MG and FaDu cells were processed for western blot and MA5-51296 detected a band in every cell line. No band was detected following IP (2 µg Ab used). In IF (1:1200 ab dilution), comparable staining intensity was observed in both KO and WT cells.

We highly encourage other scientists to share their observations.
