Aat Bioquest Cyanine 3 monosuccinimidyl ester [equivalent to Cy3® NHS ester]
A variety of cyanine 3 (Cy3®) dyes has been used to label biological molecules for fluorescence imaging and other fluorescence-based biochemical analysis. They are widely used for labeling peptides, proteins and oligos etc.
Aat Bioquest 6-TAMRA cadaverine
6-TAMRA cadaverine is a building block for developing fluoresceinated bioconjugates. It is also a fluorescent transglutaminase substrate to label proteins by transaminidation.
Aat Bioquest 5(6)-TAMRA Maleimide [Tetramethylrhodamine-5-(and-6)-maleimide] *Mixed isomers*
Tetramethylrhodamine-5-(and-6)-maleimide is an excellent reagent for preparing orange fluorescent bioconjugates through thiol modifications of peptides, nucleotides, nucleic acids and proteins.

Mca-(Asn670,Leu671)-Amyloid Beta/A4 Protein Precursor770 (667-676)-Lys(Dnp)-Arg-Arg amide Trifluoroacetate, Mca-Ser-Glu-Val-Asn-Leu-Asp-Ala-Glu-Phe-Arg-Lys(Dnp)-Arg-Arg-NH2, 438625-61-7, C86H125N27O29, Mr 2001.10, 1mg. Mca-(Asn670,Leu671)-APP770 (667-676)-Lys(Dnp)-Arg-Arg amide. This fluorescent (FRET) peptide substrate contains the 'Swedish' Lys-Met/Asn-Leu mutation of the amyloid precursor protein (APP) b-secretase cleavage site. Mca-SEVNLDAEFRK(Dnp)RR-amide has been used for assaying b-secretase-like activity of thimet oligopeptidase (TOP, EC 3.4.24.15). The results suggested that TOP is a potential b-secretase candidate and is involved in the processing of APP in vivo.
Medchemexpress LLC L-ANAP hydrochloride | 00-00-0 | 99.9% | 308.76 | C15H17ClN2O3 | 10 MG
L-ANAP hydrochloride is a genetically encodable, polarity-sensitive fluorescent unnatural amino acid supplied as a hydrochloride salt for site-specific incorporation into proteins and environment-sensitive fluorescence studies. It is used to monitor local polarity and conformational changes in molecular and cellular assays.
- Genetically encodable noncanonical amino acid for site-specific incorporation.
- Polarity-sensitive fluorescence reports local environment and conformational changes.
- High purity suitable for sensitive biochemical and fluorescence assays.
- Available in small research-scale quantities and as a DMSO solution for convenience.
- Stable when stored sealed at 4°C; in solvent, store at -80°C for long-term storage.
