Caption
Both ENCODE submitter and reviewer have agreed that this is a well-established antibody lot. Hence it does not require additional validation as standardized by the ENCODE Consortium.
Submitter comment
The lab requests that this is considered a well-documented antibody lot and therefore does not require additional validation.
Reviewer comment
Dr. Peggy J Farnham: I would support a “no additional validation needed” classification for this antibody.

EZH2 (Homo sapiens)
Method: ChIP-seq comparison
Attachment PDF Icon
compliant
Caption
This validation relies on the use of antibodies to a chromatin regulator and a functionally related histone modification in A673 cells, and the demonstration that highly similar (>0.9) patterns of enrichment are obtained with each antibody. The first antibody is to phosphorylated EZH2 (PchAb 1206, ENCAB913HCF), and the second antibody is to H3K27me3 previously characterized to Encode standards (PchAb 848, ENCAB036YAO).

Caption
We performed a WB using 0.7ug unmodified recombinant Histone H3 (Millipore 14-494), 20ug of HeLa nuclear lysate and 20ug of K562 nuclear lysate. Lysates were resolved by electrophoresis on a 4-12% bis-tris gel. After separation, the samples were transferred to a nitrocellulose membrane with an Invitrogen iBlot system. Membrane was blocked for an hour at room temperature, with 5% nonfat dry milk in TBST. The primary antibody was diluted in TBST and 5% BSA at the appropriate concentration over night at 4C. Membrane was washed and blotted with secondary HRP-conjugated antibody for 1 hour at room temp. Detection was made with Optiblot ECL Detect Kit (ab133406) for 1 min. Band of expected size (~98kDa) visualized in both nuclear lysates and could not be detected in the unmodified recombinant Histone H3. Antibody seems to be specific since no reactivity with non histone proteins or unmodified histones was detected.

Caption
K562 whole cell lysate was immunoprecipitated using primary antibody, and the IP fraction along side a whole cell lysate were loaded on a CriterionXT gel and separated. After separation, the samples were transferred using a wet transfer. Blotting with primary (same as that used for IP) and secondary HRP-conjugated antibodies was performed. Band of expected size visualized representing strongest signal in the lane (IP-1).
