Immunofluorescence analysis of IP3 Receptor I was done on 70% confluent log phase SH-SY5Y cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with IP3 Receptor I Rabbit Polyclonal Antibody (PA1901) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

PA1-901 detects inositol 1,4,5-trisphosphate receptor type-I (IP3R-I) from canine, mouse and rat tissues.
PA1-901 has been successfully used in Western blot, immunohistochemistry, immunofluoresence and immunoprecipitation procedures. By Western blot, this antibody detects an ~240 kDa protein representing IP3R-I from rat and mouse brain extract. Immunohistochemical staining of IP3R-I in rat cerebellum with PA1-901 results in staining of Purkinje cells.
PA1-901 immunizing peptide corresponds to amino acid residues 1829-1848 from human IP3R-I. This sequence is completely conserved in human, mouse, and rat IP3R-I. PA1-901 immunizing peptide (Cat. # PEP-019) is available for use in neutralization and control experiments.
Intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate. Involved in the regulation of epithelial secretion of electrolytes and fluid through the interaction with AHCYL1 (By similarity). Plays a role in ER stress-induced apoptosis. Cytoplasmic calcium released from the ER triggers apoptosis by the activation of CaM kinase II, eventually leading to the activation of downstream apoptosis pathways.
