|Application ||WB, E|
|Description||Proteinase 3, also known as PRTN3. PRTN3 is a serine protease enzyme expressed mainly in neutrophil granulocytes. Its exact role in the function of the neutrophil is unknown but in human neutrophils proteinase 3 contributes to the proteolytic generation of antimicrobial peptides. It is also the epitope of anti-neutrophil cytoplasmic antibodies (ANCAs) of the cANCA (cytoplasmic subtype) class, a type of antibody frequently found in the disease Wegener's granulomatosis.|
|Immunogen||Purified recombinant fragment of human Proteinase 3 expressed in E. Coli.|
|Formulation||Antibody are purified by protein G affinity chromatography. |
Liquid in PBS containing 50% glycerol and 0.03% sodium azide.
|Other Names||Myeloblastin, 188.8.131.52, AGP7, C-ANCA antigen, Leukocyte proteinase 3, PR-3, PR3, Neutrophil proteinase 4, NP-4, P29, Wegener autoantigen, PRTN3, MBN|
|Dilution||WB~~1/500 - 1/2000|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Proteinase 3 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Polymorphonuclear leukocyte serine protease that degrades elastin, fibronectin, laminin, vitronectin, and collagen types I, III, and IV (in vitro) and causes emphysema when administered by tracheal insufflation to hamsters.|
