  • Function

    LA-PF4 stimulates DNA synthesis, mitosis, glycolysis, intracellular cAMP accumulation, prostaglandin E2 secretion, and synthesis of hyaluronic acid and sulfated glycosaminoglycan. It also stimulates the formation and secretion of plasminogen activator by human synovial cells. NAP-2 is a ligand for CXCR1 and CXCR2, and NAP-2, NAP-2(73), NAP-2(74), NAP-2(1-66), and most potent NAP-2(1-63) are chemoattractants and activators for neutrophils. TC-1 and TC-2 are antibacterial proteins, in vitro released from activated platelet alpha-granules. CTAP-III(1-81) is more potent than CTAP-III desensitize chemokine-induced neutrophil activation.
  • Sequence similarities

    Belongs to the intercrine alpha (chemokine CxC) family.
  • Post-translational

    Proteolytic removal of residues 1-9 produces the active peptide connective tissue-activating peptide III (CTAP-III) (low-affinity platelet factor IV (LA-PF4)).
    Proteolytic removal of residues 1-13 produces the active peptide beta-thromboglobulin, which is released from platelets along with platelet factor 4 and platelet-derived growth factor.
    NAP-2(1-66) is produced by proteolytical processing, probably after secretion by leukocytes other than neutrophils.
    NAP-2(73) and NAP-2(74) seem not be produced by proteolytical processing of secreted precursors but are released in an active form from platelets.

Customer reviews and Q&As


Thank you for your enquiry.

For ab9554, Rabbit Anti Human NAP-2, this has been tested in Neutralisation as follows:
Neutralization: To yield one-half maximal inhibition [ND50] of the biological activity of Human NAP-2 (100.0 ng/ml), a concentration of 5.0 - 10.0 ug/ml of this antibody was required. This may need some individual optimization.

The recombinant protein used in this assay is NAP-2 protein ab9556. (or use the following:

For ab9679, Rabbit Anti Human RANTES, this has been tested in Neutralisation as follows:
Neutralization: To yield one-half maximal inhibition [ND50] of the biological activity of Human RANTES (100 ng/ml), a concentration of 0.4 – 0.6 μg/ml of this antibodywas required. This may need some individual optimization.

The recombinant protein used in this assay, is Rantes protein ab9680. (or use the following:
