Immunohistochemistry was performed on normal biopsies of deparaffinized Rat lymph node 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 1:200 with a mouse monoclonal antibody recognizing Nuclear Pore-O-Linked Glycoprotein (MA1-071) 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.

MA1-071 detects nuclear pore-O-linked glycoprotein from rat, amphibian and yeast.
MA1-071 has been successfully used in Western blot, immunofluorescence and immunoprecipitation procedures. By Western blot, this antibody detects up to eight different proteins from the nuclear pore complex (NPC) of approximately 210, 180, 145, 100, 63, 58, 54 and 45 kDa. Immunofluorescence staining of NPC O-linked glycoproteins with MA1-071 results in exclusive labeling of the NPC proteins on a wide variety of mammalian cells as well as S. cerevisiae and Xenopus. Labeling occurs exclusively at the NPC with most of the labeling at the cytoplasmic and nucleoplasmic margins.
Microinjected MA1-071 inhibits both protein import and RNA export in Xenopus oocytes.
The MA1-071 immunogen is pore complex-lamina fraction purified from rat liver nuclear envelopes.
Diffusion of metabolites and small non-nuclear molecules as well as active, mediated import of protein and export of protein and RNA through the nuclear envelope occurs through nuclear pore complexes or NPC"e;s. NPC"e;s contain up to 100 different polypeptides which have a combined mass of about 125 megadaltons. The channel available for passive transport through the NPC is about 9-10 nm in diameter while carrier mediated changes in the NPC result in a ~25 nm channel used for larger, actively transported molecules. Of the 100 polypeptides, at least 8 of these are O-linked N-acetylglycosamine-modified in mammalian cells. All of the mammalian O-linked glycoproteins contain multiple copies of phenylalanine, glycine dipeptide repeats dispersed throughout part of their sequence. Studies indicate that the NPC O-linked glycoproteins have a direct role in nuclear protein import.
