Prosurfactant Protein C was immunoprecipitated using 0.5mg Mouse Lung tissue, 5µg of Rabbit polyclonal to Prosurfactant Protein C 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, Mouse Lung tissue 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 ab90716.Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).Band: 23kDa; Prosurfactant Protein C
All lanes : Anti-Prosurfactant Protein C antibody (ab90716) at 1 µg/mlLane 1 : Lung (Human) Tissue Lysate Lane 2 : Lung (Mouse) Tissue Lysate Lysates/proteins at 10 µg per lane.SecondaryGoat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilutiondeveloped using the ECL techniquePerformed under reducing conditions.
ab90716 stained A549 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab90716 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
IHC image of Prosurfactant Protein C staining in Human normal lung formalin fixed paraffin embedded tissue section, performed on a Leica BondTM 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 ab90716, 1µg/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.For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
