Description

The NETosis Antibody Sampler Kit provides an economical means of detecting proteins involved in NETosis. The kit includes enough antibodies to perform two western blot experiments with each primary antibody.

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibodies.

Background

NETosis is a unique form of regulated cell death that is characterized by membrane rupture and the extrusion of chromatin, histones, and granular and cytoplasmic components into a web-like structure called neutrophil extracellular traps (NETs) (reviewed in 1). NETosis has been associated with host defense to pathogens as well as a number of disease states, including autoimmune diseases, thrombosis, cardiovascular diseases, and tumor progression. NETosis was identified as a response to bacterial infection and can be activated by lipopolysaccharide (LPS) as well as inflammatory pathway activators like phorbol-12-myristate-13-acetate (PMA) (2). It can occur via multiple pathways, but several key players have emerged. The calcium-dependent enzyme protein-arginine deiminase 4 (PAD4) catalyzes hypercitrullination of histones that contributes to chromatin decondensation (3,4). In addition, activation of proteases, including neutrophil elastase (ELANE), myeloperoxidase (MPO), and Cathepsin G, leads to impairment of cytoskeletal structures and degradation of histones during NETosis (5,6).

    Western blot analysis of extracts from U-937, THP-1, and HuH-6 cells, untreated (-) or treated with PNGase F (+), using Cathepsin G (E3N3O) Rabbit mAb (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). The lack of detectable Cathepsin G expression in HuH-6 cells is consistent with proteomic and transcriptomic expression profiling data, confirming specificity of the antibody.

    After the primary antibody is bound to the target protein, a complex with HRP-linked secondary antibody is formed. The LumiGLO® is added and emits light during enzyme catalyzed decomposition.

    Western blot analysis of extracts from various cell lines using Neutrophil Elastase (E9C9L) XP® Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower). As expected, neutrophil elastase protein expression is not detected in either A-498 or Jurkat cells.
