The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 69 kDa (predicted molecular weight: 69 kDa).
Use at an assay dependent concentration.
Use a concentration of 5 µg/ml.
RelevanceScc4 (Mau2) is the metazoan homologue of Scc4 in S. cerevisiae. In yeast, Scc4 binds to Scc2 to form an essential complex that loads cohesion onto chromosomes. Similarly, the Scc4 / Mau2 protein in metazoans plays a significant role in sister chromatid separation and in loading of cohesin onto chromatin. The Scc2-Scc4 complex is tethered to pre-replication complexes through the Cdc7-Drf1 protein kinase DDK.
ICC/IF image of ab46906 stained HeLa cells. The cells were 100% methanol fixed (5 min) then permeabilised using 0.1% PBS-Triton and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to further permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab46906 at 1µg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Alexa Fluor® 488 goat anti- rabbit (ab150081) IgG (H+L) preadsorbed, used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

Scc4 was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to Scc4 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-). The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation. Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab46906. Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697). Band: 69kDa: Scc4; non specific - 53kDa: We are unsure as to the identity of this extra band.
