Mix-n-Stain™ Antibody Labeling Kits are superior to Lightning-Link® labeling kits (Figure 2). Mix-n-Stain™ kits feature CF® dyes, with superior brightness and photostabilty compared to the Lightning-Link® labeling (Figure 2). In addition, Mix-n-Stain CF® dye kits are compatible with labeling in the presence of excess stabilizer protein or ascites, unlike Lightning-Link®.
