  • Function
    May be involved in collagen fiber assembly.
  • Tissue specificity
    Found in several connective tissues, especially in articular cartilages.
  • Sequence similarities
    Belongs to the small leucine-rich proteoglycan (SLRP) family. SLRP class I subfamily.
    Contains 12 LRR (leucine-rich) repeats.
  • Post-translational
    The two attached glycosaminoglycan chains can be either chondroitin sulfate or dermatan sulfate.
  • Cellular localization
    Secreted > extracellular space > extracellular matrix.

    Biglycan antibody (ab54855) at 1ug/lane + HepG2 cell lysate at 25ug/lane.
  • ab54855 (2µg/ml) staining biglycan in human spleen using an automated system (DAKO Autostainer Plus). Using this protocol there is strong cytoplasmic staining.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH6.1/ in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
  • Overlay histogram showing A431 cells stained with ab54855 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab54855, 0.5µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
