Recombinant Anti-Calmodulin 1/2/3 antibody [EP799Y] - C-terminal (ab45689)

ΔSRCR peripheral blood monocyte-derived macrophages (PMMs) still function as hemoglobin-haptoglobin (Hb-Hp) scavengers.

Porcine PMMs were incubated for 24 hours in the presence of 100 μg/mol Hb-Hp then lysed with reducing SDS sample buffer and HO-1 protein expression analyzed by western blot.

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: PBS in place of primary antibody (inset).

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. An Alexa Fluor^® 555-conjugated Goat anti-rabbit IgG polyclonal (1/400) was used as the secondary antibody.

Overlay histogram showing MCF7 (Human breast adenocarcinoma cell line) cells stained with ab45689 (red line).

The cells were fixed with methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab45689, 1/50 dilution) for 30 min at 22°C. The secondary antibody used was DyLight^® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22°C.

Isotype control antibody (black line) was rabbit monoclonal IgG (0.5µg/1x10⁶ cells) used under the same conditions.

Acquisition of >5,000 events was performed.

This antibody gave a decreased signal in MCF7 cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.
