NEW Signal-Seeker™ SUMOylation 1 Detection Kit (10 assay)

Signal Seeker SUMOylation 1 Detection Kit (10 assays, immunoprecipitation format)
$0.00

The Signal-Seeker™ line of produts have been developed to allow simple analysis of key regulatory protein modifications by specialists and non-specialists alike. The comprehensive Signal-Seeker™ kits provide an affinity bead system to isolate and enrich modified proteins from any given cell or tissue lysate. The enriched protein population is then analyzed by standard western blot procedures using a primary antibody to the target protein. 

Product Uses Include

  • Investigate transient regulatory mechanisms
  • Measure signalling events of multiple pathway member proteins 
  • Discover new modifications of your protein of interest
  • Gain insight into regulatory mechanisms
  • Measure endogenous or transiently expressed protein signalling events

Application 1: Investigate significant SUMOylation 1 events

Immunoprecipitating total SUMO1 profiles using the Signal-Seeker™ SUMOylation 1 Detection Kit  compared to older SUMO1 tools

(A) HAP1 wildtype (WT) or SUMO1 knockout (KO) lysate, was obtained using BlastR lysis and filter system. 1 mg of each lysate were incubated with 40 µg of each SUMO1 affinity reagent: ASM11-beads (Cytoskeleton), 21C7 (Invitrogen—purified), 21C7 (DSHB—supernatant), D11-beads (Santa Cruz) and conjugated SUMO1 IgG control beads (CIG03).  21C7 antibodies were captured with protein G agarose beads to enrich for SUMO-1 modified proteins. Samples were separated by SDS-PAGE and transferred to PVDF.  Enriched SUMO1 samples were analyzed by western blot using ASM01 (Cytoskeleton) antibody at 1:5000, and mouse Trubelot Ultra-HRP secondary at 1:1000 in 5% milk. Trueblot secondary was used to minimize heavy and light chain detection from 21C7 samples. 

(B): IP was performed using ASM11 as in Fig 1A.  SUMO1 modified proteins were visualized with ASM01 1:5000, and anti-mouse secondary at 1:20,000 to highlight the profile of SUMOylated proteins in the region between 64-30 kDa that may be masked by heavy and light chain interference when using unconjugated antibodies for IP.

Immunoprecipitating SUMO1 modified target proteins using the Signal-Seeker™ SUMOylation 1 Detection Kit  compared to older SUMO1 tools

HAP1 wildtype (WT) or SUMO1 knockout (KO) lysate, was obtained using BlastR lysis and filter system. 1 mg of each lysate were incubated with 40 µg of each SUMO1 affinity reagent: ASM11-beads (Cytoskeleton), 21C7 (DSHB—supernatant), and conjugated SUMO1 IgG control beads (CIG03).  21C7 antibodies were captured with protein G agarose beads to enrich for SUMO-1 modified proteins. Samples were separated by SDS-PAGE and transferred to PVDF.  Target proteins: (A) TFII-I, RanGAP1, and (B) schmd1 were analyzed for their SUMO1 modified forms by western blot. Anti-rabbit-HRP labeled secondary antibody was used at 1:10,000. All three primary antibodies are rabbit polyclonal antibodies, and should not bind heavy and light chain fragments from the IP antibody.

Other experiments that could be attempted in this area of research include:

• Pharmacological investigation of SUMOylating  and de-SUMOylating enzymes involved in regulation of target proteins.

• Investigate SUMOylation under a variety of different growth factors or drug treatments.

• Examine the interaction of SUMOylated target proteins with its downstream effectors.

• Examine crosstalk between SUMOylation 1 and other PTMs for target proteins.
