Immunohistochemistry was performed on cancer biopsies of deparaffinized Human cervical carcinoma tissue. 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 rabbit polyclonal antibody recognizing PMCA2 ATPase (PA1-915) 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.

PA1-915 detects calcium pump of the plasma membrane 2 (PMCA2 ATPase) from human and rat and porcine tissues and cells.
PA1-915 has been successfully used in Western blot procedures. By Western blot, this antibody detects an ~127 kDa protein and an ~133 kDa protein representing PMCA2a and PMCA2b ATPase, respectively, from rat brain microsomal fractions.
PA1-915 immunizing peptide corresponds to amino acid residues 5-19 from human PMCA2 ATPase protein. This sequence is completely conserved between human and rat PMCA2 ATPase.
The calcium pump of the plasma membrane, termed PMCA ATPase, pumps calcium from the cytosol to the extracellular space. This membrane-bound enzyme is related to a number of other ATPases including the SERCA ATPase and the sodium/K+ pump.
There are four different genes encoding PMCA ATPase and studies have revealed 20 isoforms of the pump generated by alternate splicing of the primary gene products. mRNA distribution studies show that gene products 1 and 4 are transcribed in most tissues, however, products 2 and 3 are more tissue specific. Transcription of the splicing variants has also been found to be tissue specific. In the pancreas, where insulin secretion is calcium dependent, the beta cells only express the 4b isoform, however the alpha and gamma cells express both 4a and 4b isoforms. Studies have also shown that different splice variants have different affinities for calcium and calmodulin.
