|IHC-Fr||Use at an assay dependent concentration.|
ab45689 immunoprecipitating Calmodulin. 10µg of cell lysate was incubated with primary antibody at a dilution of 1/20 and VeriBlot for IP secondary antibody (HRP) (ab131366) at a dilution of 1/10000.
Lane 1: Human skeletal muscle lysate (10ug)
Lane 2: Human skeletal muscle lysate
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab45689 in Human skeletal muscle lysate
ab45689 staining Calmodulin in NIH/3T3 (mouse embryo) cells by flow cytometry. Cells were fixed with 4% paraformaldehyde and the sample was incubated with the primary antibody at a dilution of 1/100. A goat anti rabbit IgG (Alexa Fluor® 488) at a dilution of 1/2000 was used as the secondary antibody.
Isoytype control: Rabbit monoclonal IgG (Black)
Unlabelled control: Cell without incubation with primary antibody and secondary antibody (Blue)
ab45689 staining Calmodulin in human testis tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and antigen retrieval was by heat mediation in a EDTA buffer. Samples were incubated with primary antibody at a dilution of 1/2000. A goat anti-rabbit IgG H&L (HRP) ab97051 was used as the secondary antibody at a dilution of 1/500.
Negative control 1: PBS in place of primary antibody.
Blocking and diluting buffer: 5% NFDM/TBST
Blocking and Diluting buffer: 5% NFDM/TBST
ab45689 staining Calmodulin in Mouse brain tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with acetone and blocked with 10% Serum for 60 minutes at 4°C. Samples were incubated with primary antibody (1/100 in PBS + 0.1% Triton) for 12 hours at 4°C. A Alexa Fluor® 555-conjugated Goat anti-rabbit IgG polyclonal (1/400) was used as the secondary antibody.
ICC/IF image of ab45689 stained MCF7 cells. The cells were 100% methanol fixed (5 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 (ab45689, 1/1000 dilution) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit 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.
