Immunocytochemistry/Immunofluorescence: LOX propeptide Antibody TA336520 - HepG2 cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X PBS + 0.05% Triton-X100. The cells were incubated with anti-LOX propeptide at 5 ug/ml overnight at 4C and detected with an anti-rabbit Dylight 488 (Green) at a 1:500 dilution. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.

  Immunohistochemistry-Paraffin: LOX propeptide Antibody TA336520 - IHC analysis of a formalin fixed paraffin embedded tissue section of mouse intestine using 1:200 dilution of rabbit anti- LOX propeptide (LOX-PP) antibody. The staining was developed using HRP labeled anti-rabbit secondary antibody and DAB reagent, and nuclei of cells were counter-stained with hematoxylin. This LOX-PP antibody generated a strong cytoplasmic staining in the epithelial and other cells with a majority of the signal localizing to luminal end of columner epithelial cells. There appears to be some nuclear positivity also which might be a nuclear variant of LOX-PP.

  Western Blot: LOX propeptide Antibody TA336520 - Total protein from human and mouse brain was separated on a 12% gel by SDS-PAGE, transferred to 0.2 um PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 0.5 ug/ml anti-LOX propeptide in block buffer and detected with an anti-rabbit HRP secondary antibody using chemiluminescence.

  Western Blot: LOX propeptide Antibody - BSA Free TA336520 - LOX propeptide Antibody TA336520 - Human VSMC were transduced with a lentiviral vector encoding for full-length LOX (pLOX; black bars), LOX-PP (pLOX-PP; grey bars) or with the corresponding empty vector (pLVX; V; white bars). (a) Immunoblots corresponding to mature LOX (mLOX; left panel) & LOX-PP (right panel). The position of the pro-enzyme (ProLOX, right panel), detected with the antibody against the propeptide. GAPDH was analyzed as a loading control. Displayed blots are not cropped from different gels or different parts of the same gel. Representative immunoblots from 3 independent experiments were shown.

• Background: Lysyl oxidase (LOX) is a critical enzyme in extracellular matrix biosynthesis as well as in the maintainance of normal bone phenotype. It is synthesized/secreted as a 50-kD proenzyme 'pro-LOX' which is then processed to 30-kD mature enzyme 'LOX' and 18-kD lysyl oxidase propeptide 'LOX-PP' by extracellular procollagen C-proteinases (BMP1, Tll1, and Tll2). LOX-PP has been proposed to implicate in the maintenance of inactive state of LOX within the secretory pathway and to act as intramolecular chaperones which facilitate the accurate protein folding/targeting to correct destinations. LOX-PP involves tumor suppression by inhibiting RAS-dependent cellular transformation and its expression has also been associated with inhibition of anchorage-independent progression as well as migration and growth suppression xenografts in Her-2/neu-driven breast cancer. LOX-PP also inhibits PI3K/AKT and ERK1/2 MAP kinase pathways, as well as the levels of downstream NF-kB/cyclin D1 signals in certain cancers - breast, pancreatic, lung, prostate and oral cancers. LOX-PP has also been shown to inhibit DNA synthesis in rat's VSMCs cultures, osteoblast proliferation and FGF-2 signaling.
• Synonyms: MGC105112
• Note: This LOX propeptide antibody is useful for Immunocytochemistry/Immunofluorescence, Immunohistochemistry-Paraffin and Western Blot where a band is seen at ~18 kDa. The strong band at 50 kDa and smear of bands that run between 46 kDa and 50 kDa are glycosylated and non-glycosylated forms of pro-lysyl oxidase. Bands between 28-36 kDa are glycosylated propeptide. The variation in MW depends on the extent of glycosylation.
