Immunoprecipitation of DEC-1 from K562 cells using NB100-1800. Lane 1: input nuclear lysate. Lane 2: material immunoprecipitated with NB100-1800. Lane 3: material immunoprecipitated using control IgG. Band A was excised from gel and subject to analysis by mass spectrometry. Expected band size ~51kD.

Caption
IP followed by mass spectrometry: Briefly, protein was immunoprecipitated from K562 whole cell lysates using NB100-1800, and the IP fraction was loaded on a 10% polyacrylamide gel (NuPAGE Bis-Tris Gel) and separated with an Invitrogen NuPAGE electrophoresis system. The gel was silver-stained, gel fragments corresponding to the bands indicated were excised and destained using the SilverSNAP Stain for Mass Spectrometry (Pierce). Then proteins were treated with trypsin using the in-gel digestion method. Digested proteins were analyzed on a LTQ-Orbitrap (Thermo Scientific) b the nanoLC-ESI-MS/MS technique. Peptides were identified by the SEQUEST algorithm and filtered with a high confidence threshold (protein false discovery rate <1%, 2 peptides per protein minimum).

A. Western blots on nuclear lysates from cell lines GM12878 (Lane1), K562 (Lane2), HeLaS3 (Lane3), and HepG2 (Lane4). B. Immunoprecipitation was performed on nuclear lysates from K562 cells using antibody NB100-1800 against Dec1. Lane1: Nuclear lysate. Lane 2: Unbound material from immunoprecipitation with NB100-1800. Lane 3: Bound material from immunoprecipitation with NB100-1800. Lane 4: Bound material from control immunoprecipitation with rabbit IgG. Arrow indicates band of expected size (18kD) that is highly enriched in the specifically immunoprecipitated fraction. Bands indicated by * in K562 immunoprecipitate are IgG heavy and light chains. A unique band of ~49kD is detected by Western blotting with NB100-1800 in multiple human cell lines and immunoprecipitation from K562 nuclear lysate efficiently enriches a single protein of ~49KD. Based on these observations, this antibody meets this ENCODE criterion.

Immunoprecipitation of DEC1 from K562 cells using NB100-1800. Lane 1: input nuclear lysate, Lane 2: material immunoprecipitated with NB100-1800, Lane 3: material immunoprecipitated using control IgG. Bands A was excised from the gel and subject to analysis by mass spectrometry. IP followed by mass spectrometry: Briefly, protein was immunoprecipitated from K562 whole cell lysates using NB100-1800, and the IP fraction was loaded on a 10% polyacrylamide gel (NuPAGE Bis-Tris Gel) and separated with an Invitrogen NuPAGE electrophoresis system. The gel was silver-stained, gel fragments corresponding to the bands indicated were excised and destained using the SilverSNAP Stain for Mass Spectrometry (Pierce). Then proteins were trypsinized using the in-gel digestion method. Digested proteins were analyzed on an LTQ-Orbitrap (Thermo Scientific) by the nanoLC-ESI-MS/MS technique. Peptides were identified by the SEQUEST algorithm and filtered with a high confidence threshold (Protein false discovery rate < 1%, 2 peptides per protein minimum). We report 12 proteins identified in band A, although 3 of these are also present in a control immunoprecipitation and are thus likely to present due to non-specific association with the IP matrix. Of the specifically immunoprecipitated proteins, DEC1 is the most abundant (42 peptides). Based on these observations, this band is likely due to the presence of immunoprecipitated DEC1 and NB100-1800 meets the ENCODE standard for validation by this criterion.
