Anti-esiB

Make to order. Production time: 70-80 business days. Deliverables: 1. 200 µg antigen (used as positive control), 2. 1 ml pre-immune serum (used as negative control) , 3. Rabbit polyclonal antibody, antigen affinity purified. Quality Guarantee: 1. Antibody purity > 90% confirmed by SDS-PAGE, 2. Antibody titer > 1: 64,000 confirmed by ELISA, 3. WB positive with the immunogen protein (not applicable for synthetic peptide). Applications: ELISA, WB (positive for the recombinant immunogen protein/peptide). Buffer: Preservative: 0.03% Proclin 300, Constituents: 50% Glycerol, 0.01M PBS, pH 7.4. Protein function: Upon host (human neutrophil) infection interferes with productive FCAR signaling, inhibiting secreted IgA (SIgA) effector functions and probably avoiding neutrophil activation. Inhibits the SIgA-mediated oxidative burst by neutrophils, decreases generation of ROS (reactive oxygen species) by neutrophils and reduces chemotaxis by neutrophils, all of which are SIgA effector functions used to stimulate the immune response. Does not block SIgA-binding to its receptor (FCAR) on neutrophils, but it decreases SIgA-stimulated phosphorylation of cytoplasmic proteins, including phospholipase C-gamma and MAP kinases, all actions that may be advantageous to the pathogen.
