Osteocalcin Antibody | Monoclonal Anti-Bovine Osteocalcin (Clone OC4-30, OCG2, OCG3 and OCG4)

Monoclonal Anti-Bovine Osteocalcin Antibody (Clones OC4-30,OCG2, OCG3 and OCG4) is raised against bovine osteocalcin and recognizes both bovine and human osteocalcins. Clone OC4-30 is specific for position 17 gamma-carboxylated osteocalcin and does not recognize decarboxylated osteocalcin. Osteocalcin epitopes used to generate Clones OCG2, OCG3 and OCG4 are amino acids 45-49, amino acids 21-31 and amino acids 4-9, respectively. This collection of osteocalcin antibody clones facilitates osteocalcin immunohistochemistry studies which can also be performed on paraffin-embedded tissues (as described in the Resources). In addition to cross-reactivity with bovine and human osteocalcin, clones OCG4-30, OCG3 and OCG4 are also capable of recognizing osteocalcin in several other species as listed. For species-specific osteocalcin detection, Takara Bio offers additional osteocalcin antibody products.

  • All clones can be used for Western blot under reducing or non-reducing conditions.
  • Clones OCG4-30, OCG2 and OCG4 can be used for osteocalcin immunohistochemistry on frozen and paraffin-embedded tissue sections.
  • Clone OCG3 can also be used for osteocalcin immunohistochemistry on frozen tissue sections. Is has weaker reactivity on paraffin-embedded tissue sections than the other clones.
