Technical Data
Fractalkine, Recombinant, Human (Neurotactin)
Molecular Biology Storage: -20CShipping: Blue Ice
Recombinant corresponding to 76aa from human Fractalkine expressed in E. coli.

Molecular Weight:

Endotoxin: 0.1ng/ug

Biological activity of recombinant human fractalkine is determined by measuring concentration dependent chemotaxis with human T cells. A concentration range of 5-10 ng/ml produces significant chemotaxis. The optimal concentration should be determined for each specific application. Fractalkine is a CX3C chemokine.

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:
Source: E. coli
Purity: ~98% (SDS-PAGE, HPLC)
Concentration: Not determined
Form: Supplied as a lyophilized powder. BSA free. Reconstitute with sterile dH2O to 0.1-1mg/ml.
