Neutrophil Elastase タンパク質・ペプチド 製品一覧
Activity: 20-22 units per mg protein.
One unit is defined as the amount of enzyme that hydrolyzes one micromole of Meo-suc-ala-pro-val-pNA per minute at 25°C in 100 mM Tris-HCl, pH 7.5, with 500 mM NaCl.
Prepared from whole blood shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA approved tests.
精製度> 95 % SDS-PAGE.

Our Abpromise guarantee covers the use of ab91099 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Reconstitute in 50 mM Na acetate pH 5.5 with 150 mM NaCl.
Dissolve at a concentration of 1 to 2 mg/mL and store at -20 degrees C. If not immediately frozen, this enzyme should be used promptly to limit loss of activity.
Protein Determination: Extinction Coefficient (E) 0.1% at 280nm, 1cm pathway = 0.985.
Concentration information loading...
Shipped at 4°C. Store at -20°C. Avoid freeze / thaw cycle.
Constituent: 100% Elastase
This product is an active protein and may elicit a biological response in vivo, handle with caution.
再構成After initial centrifugation, we suggest the addition of 50 mM Na Acetate, pH 5.5, with 150 mM NaCl to the original volume, followed by gentle swirling and/or vortexing to ensure adequate homogenization.
- Bone marrow serine protease
機能Modifies the functions of natural killer cells, monocytes and granulocytes. Inhibits C5a-dependent neutrophil enzyme release and chemotaxis.
組織特異性Bone marrow cells.
関連疾患Defects in ELANE are a cause of cyclic haematopoiesis (CH) [MIM:162800]; also known as cyclic neutropenia. CH is an autosomal dominant disease in which blood-cell production from the bone marrow oscillates with 21-day periodicity. Circulating neutrophils vary between almost normal numbers and zero. During intervals of neutropenia, affected individuals are at risk for opportunistic infection. Monocytes, platelets, lymphocytes and reticulocytes also cycle with the same frequency.
Defects in ELANE are the cause of neutropenia severe congenital autosomal dominant type 1 (SCN1) [MIM:202700]. SCN1 is a disorder of hematopoiesis characterized by a maturation arrest of granulopoiesis at the level of promyelocytes with peripheral blood absolute neutrophil counts below 0.5 x 10(9)/l and early onset of severe bacterial infections.
配列類似性Belongs to the peptidase S1 family. Elastase subfamily.
Contains 1 peptidase S1 domain.
