Product Information

anti-GFP VHH/ Nanobody conjugated to a fluorescent dye for IF/ microscopy.

DescriptionThe GFP-Booster stabilizes, enhances, and reactivates the signal of GFP-fusion proteins. Due to its small size, the GFP-Booster enables higher image quality in epifluorescence, confocal, and super-resolution microscopy

• Considerably higher tissue penetration rates

• Superior accessibility and labelling of epitopes in crowded cellular/organelle environments

• Less than 2 nm epitope-label displacement minimizes linkage error

• Monovalent VHHs do not cluster their epitopes

• Validation: structure and function characterized

• Consistent and reliable performance due to recombinant production

ApplicationsIF, IHC, ICC
Specificity/TargetCFP, AcGFP, EGFP, GFP, GFP S65T, mClover, EGFP A206K, pHluorin, PA-GFP, sfGFP, TagGFP, TagGFP2, Citrine, Ecitrine, EYFP, Venus, YFP, Ypet

this is the second time that I purchase the GFP booster, first time i used the 488 and it worked great, this time I got the 568. Tissue used is colon and the two BoosterGFP worked differently, with the 568 having lots of trouble (lot issue???)
