Alexa Fluor® 647 Protein Labeling Kit
from
Molecular Probes (Invitrogen)
Description
From start to finish, it takes less than three hours to label a protein and purify the resulting conjugate using the Alexa Fluor 647 Protein Labeling Kit. Although optimized for 1 mg of an IgG antibody, this kit can be used to make conjugates of other proteins larger than ~30,000 daltons. The kit provides sufficient material to perform three protein conjugations and purifications. To label 100 ?g of an IgG, we have the Alexa Fluor 647 Monoclonal Antibody Labeling Kit (A-20186). Alternatively, the reactive dye provided in both of these kits is available separately (A-20006, A-20106).
