Detects human CXCL7/NAP‑2 in direct ELISAs and Western blots. In direct ELISAs, approximately 25% cross-reactivity with recombinant mouse (rm) MIP-2 is observed, 10% cross-reactivity with recombinant human (rh) GRO alpha, rhIL-8, rhCINC-2 alpha, and rhGRO beta is observed, and 5% cross-reactivity with recombinant rat (rr) CINC-1, rrCINC-2 beta, rhGCP-2, rmKC, rhMIG, and rhGRO beta. is observed.
Polyclonal Goat IgG
E. coli-derived recombinant human CXCL7/NAP-2 Ala59-Asp128 Accession # P02775
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Detection of Human CXCL7/NAP‑2 by Simple WesternTM. Simple Western lane view shows lysates of human blood platelets, loaded at 0.2 mg/mL. A specific band was detected for CXCL7/NAP‑2 at approximately 7 kDa (as indicated) using 10 µg/mL of Goat Anti-Human CXCL7/NAP‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF393) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Neutrophil Activating Peptide 2 (NAP-2), Connective Tissue Activating Protein III (CTAP‑III) and beta -thrombogulin ( beta ‑TG), are proteolytically processed carboxyl-terminal fragments of platelet basic protein (PBP) which is found in the alpha-granules of human platelets. NAP-2 is a member of the CXC chemokines. Similar to other ELR domain containing CXC chemokines such as IL-8 and the GRO proteins, NAP-2 has been shown to bind CXCR2 and to chemoattract and activate neutrophils. Although CTAP-III, beta -TG and PBP represent amino-terminal extended variants of NAP-2 and possess the same CXC chemokine domains, these proteins do not exhibit NAP-2 activity. It has been shown that the additional amino-terminal residues of CTAP-III masks the critical ELR receptor binding domain that is exposed on NAP-2 and may account for lack of NAP-2 activity.
