IRDye® 680LT Protein Labeling Kits

IRDye 680LT Protein Labeling Kits can be used to label antibodies and other proteins for applications such as Western blots and microscopy.

High Molecular Weight

Optimized for labeling 1.0 mg of protein with molecular weight 45 - 200 kDa.

This kit contains:

• 3 x 0.125 mg IRDye 680LT Reactive Dye vials
• 0.5 mL 1 M Potassium Phosphate (K₂HPO₄), pH 9
