Beschreibung

AA Sequence of recombinant protein: AELRCMCIKT TSGIHPKNIQ SLEVIGKGTH CNQVEVIATL KDGRKICLDP DAPRIKKIVQ KKLAGDESAD. Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human NAP-2 (CXCL7). Anti-Human NAP-2 (CXCL7)-specific antibody was purified by affinity chromatography and then biotinylated. Sandwich ELISA: To detect Human NAP-2 by sandwich ELISA (using 100 μL/well) a concentration of 0.25-1.0 μg/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with PeproTech Polyclonal Anti-Human NAP-2 (CXCL7) (500-P03) as a capture antibody, allows the detection of at least 2000-4000 pg/mL of Recombinant Human NAP-2. Western Blot: To detect Human NAP-2 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL. When used in conjunction with compatible development reagents the detection limit for Recombinant Human NAP-2 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions. 500-P03BT-1MG will be provided as 2 x 500 μg

Members of the a-chemokine subfamily of inducible, secreted, pro-inflammatory cytokines contain a similar motif, in which the first two cysteine residues are separated by a single residue (Cys-X-Cys), and are also chemotactic for neutrophils. The platelet basic protein (PBP), a member of the a-chemokine family, resides in the a-granules of platelets and is released upon their activation. Proteolytic cleavage of the amino terminus of PBP leads to the generation of several peptides, which include mature PBP, connective tissue-activating peptide III (CTAP III, also designated low affinity platelet factor IV (LA-PF4)), b-thromboglobulin (b-TG), and neutrophil-activating peptide 2 (NAP-2). PBP and its N-truncated derivatives mediate inflammation and wound healing. Specifically, NAP-2 activates chemotaxis and degranulation in neutrophils during inflammation. The gene encoding human PBP maps to chromosome 4q12-q13.
