NAP2 (Neutrophil Activating Protein 2, CXCL7, C-X-C motif chemokine 7, PPBP, pro-platelet basic protein)
2ug
Molecular Biology Storage: -20CShipping: Blue Ice
Source:
Recombinant corresponding to 70aa from human NAP-2 expressed in E. coli.

Molecular Weight:
~8kD

Biological Activity:
Determined by measuring the dose dependent stimulation of chemotaxis of human neutrophils in a modified Boydon Chamber. Significant chemotaxis is observed with 50ng/ml. The suggested concentration range for in vitro studies is 50ng/ml. The optimal concentration should be determined for each specific application.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
~8kD
Purity: ~98% (SDS-PAGE)
Concentration: Not determined
Form: Supplied as a lyophilized powder. BSA free. No preservative added. Reconstitute with sterile dH2O to 0.1-1mg/ml.
