- Caption
- Because the overlap of the top 40% of peaks from datasets derived from antibodies sc-13125 and SAB1404509 (compared using standard ENCODE scoring methods) exceeds the recommended threshold of 80%, both antibodies meet this criterion for validation.

UBTF (Homo sapiens)
not reviewed
- Caption
- Using antibody SAB1404509 or sc-13125, we observe a major band in Western blots on lysates from cell lines K562, HeLa S3, HepG2, and, at lower intensity, GM12878 that migrates at a position consistent with the predicted size (~89kD) of UBF/UBTF (Panels A,B). This band is specifically immunoprecipitated from K562 lysates by each antibody (Panels C,D). Based on this, SAB1404509 and sc-13125 are validated by this criterion.

- Immunoprecipitation was performed on nuclear extracts from the cell line K562 using the antibody SAB1404509. Lane 1: input nuclear lysate. Lane 2: material immunoprecipitated with antibody. Lane 3: material immunoprecipitated using control IgG. Marked bands were excised from gel and subjected to analysis by mass spectrometry. Target molecular weight: 89.4.

- IP followed by mass spectrometry. Briefly, protein was immunoprecipitated from K562 nuclear cell lysates using the antibody SAB1404509, and the IP fraction was loaded on a 10% polyacrylamide gel (NuPAGEBis-Tris Gel) and separated with an Invitrogen NuPAGE electrophoresis system. The gel was stained by ColloidialCoomassie G-250 stain, gel fragments corresponding to the bands indicated were excised. Then proteins were trypsinized using the in-gel digestion method. Digested proteins were analyzed on an Orbitrap Elite mass spectrometer (Thermo Scientific) by the nanoLC-ESI-MS/MS technique. Peptides were identified by the SEQUEST algorithm and filtered with a high confidence threshold (Peptide false discovery rate < 1%, 2 unique peptides per protein minimum, mass error < 10 ppm).
