Immunohistochemistry was performed on normal deparaffinized Human heart tissue tissues. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:20 with a rat monoclonal antibody recognizing HCN4 (MA3-903) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

MA3-903 detects HCN4 from human, mouse, and rat samples.
MA3-903 has been successfully used in Western blotting and immunohistochemistry procedures. By Western blot MA3-903 detects a ~132 KDa band representing HCN4.
The MA3-903 immunogen is a synthetic peptide sequence corresponding to residues S H G S L L L P P A S S P P P P Q V P Q R R G T P P L T P G R L T Q D L K L of HCN4.
MA3-903 clone SHG 1E5 is a rat monoclonal hybridoma. This antibody was produced by immunizing a rat, isolating the spleen cells, creating the hybridoma and successively injecting these cells into a mouse to produce ascites.
HCN4 is a member of the family of hyperpolarization-activated and cyclic-nucleotide-gated (HCN) channels. HCN currents have been linked to pacemaker activity in the heart and brain, resting potential control, as well as neuronal plasticity. It has been shown that HCN4 channels function as receptors for sour taste, and are associated with pacemaker potential generation in the sinoatrial node.
