Aat Bioquest Cyanine 5 monosuccinimidyl ester [equivalent to Cy5® NHS ester]
A variety of cyanine 5 ( Cy5®) 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 HIS Lite™ Cy5 Bis NTA-Ni Complex
Polyhistidine is one of the most popular affinity tags incorporated into recombinant proteins. It can be inserted either at the N- or C-terminus, and expressed in a variety of hosts.
Aat Bioquest DBCO-Cy5
This azadibenzocyclooctyne-cyanine dye derivative is a versatile labeling reagent for detection of azide containing molecules or compounds. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne cycloaddition reactions.
Aat Bioquest Sulforhodamine 101 sulfonyl chloride [Texas Red®] *CAS 82354-19-6*
Sulforhodamine 101 acid chloride (also called Texas Red®) is the most popular labeling reagent of sulfonyl chloride. It is quite unstable in water, especially at the higher pH required for reaction with aliphatic amines.

Cayman Chemical BIotIn-X-NHS 250mg
A compound used to attach biotin to primary amines, such as those found on lysines on the surface of proteins; contains six-atom spacer arm
AdipoGen Rhodamine 110 chloride, 13558-31-1, MFCD00042009, 1 g
MF: C20H14N2O3 . HCl, MW: 366.802, ≥97%, Appearance: Red to red-brown crystalline or powder. Fluorescent dye. Fluorophore standard that is widely used in enzyme assay systems. Precursor for a variety of R110-based enzyme substrates for flow cytometric measurements. Used as a calibration standard for R110-based enzyme substrates. Compared to AMC and AFC enzyme substrates, fluorogenic R110 substrates are generally more sensitive, giving longer absorption and fluorescence wavelength than AMC and AFC substrates.
Biotium Human Transferrin, CF488A Conjugate, 1 mg
Transferrin is a glycoprotein that binds iron for delivery to vertebrate cells through receptor-mediated endocytosis. After binding to its receptor on the cell surface, transferrin is rapidly internalized by invagination of clathrin-coated pits with formation of endocytic vesicles, the acidic environment favors dissociation of iron from the transferrin-receptor complex. Following the release of iron, the apotransferrin is recycled to the plasma membrane where it is released from its receptor to scavenge more iron. Fluorescent conjugates of human transferrin can be used as tracers for investigation of endocytosis by microscopy. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Green fluorescent CF488A dye has excitation/emission at 490/515 nm.
