Immunofluorescence analysis of PDIA6 (P5) was performed using 70% confluent log phase A-549 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 PDIA6 Rabbit Polyclonal Antibody (PA3-008) at 1:250 dilution 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 (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 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

PA3-008 detects P5 protein in human samples.
PA3-008 has successfully been used in Western blot procedures. By Western blot, this antibody detects an ~50 kDa protein representing P5 in human fibrosarcoma HT 1080 cell lysate.
The PA3-008 immunogen is a synthetic peptide corresponding to residues D(476) I D L S D V E L D D L G K D E L(492) of human P5. This peptide (Cat. # PEP-224) is available for use in neutralization and control experiments.
P5 is a novel protein that was originally identified in humans. Functionally, P5 has been shown to have peptide binding ability and chaperone activity specific to certain proteins. P5 shares several structural similarities to PDI, an important protein of the ER. The deduced amino acid sequence of P5 shows that it contains the ER retention signal KDEL. P5 also contains two CXXC-like motifs, a motif responsible for oxidoreductase activity. These two CXXC motifs are found on the N- and C-terminus of the protein, one at each end. Studies suggest that the N-terminal CXXC motif is more important than the second for isomerase activity. Contrary to most of the PDI-like proteins, P5 is not stress-inducible.
