IRDye and VRDye Labeling Kits and Reagents

  • For labeling of IgG antibodies
  • Cost-effective alternatives to antibody labeling services
  • May also be used for labeling of 50-200 kDa proteins

VRDye labeling kits are cost-effective alternatives to expensive, time-consuming, custom antibody labeling services. The High MW kits are optimized for labeling 1 mg of an IgG antibody. The High MW-Microscale kits are optimized for labeling 100 µg of an IgG antibody. These kits may also be used to label proteins spanning the molecular weight range of 50 kDa to 200 kDa.

IRDye Labeling Kits contain IRdyes functionalized with an NHS ester reactive group that will couple to free amino groups and form a stable conjugate. Labeled proteins may be used for Western blots, In-cell Western Assays, in vivo imaging, and other applications.

Kits contain reagents sufficient for labeling of 3 x 1mg of protein, microscale kits for 3 x 100 µg of protein.
