Anti-ALK-1抗体(ab68703)

ALK-1 contains a number of potential glycosylation and phosphorylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.

ALK-1 was immunoprecipitated using 0.5mg K562 whole cell extract, 5µg of Rabbit polyclonal to ALK-1 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, K562 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 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab68703.

Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).

Band: 62kDa; ALK-1, non specific - as present in control (lane 2); We are confident this was due to slight lane contamination and the band seen in the IP lane is our target of interest.

IHC image of ALK-1 staining in normal human liver formalin fixed paraffin embedded tissue section, performed on a Leica Bond^TM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab68703, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
