Aat Bioquest Tide Quencher™ 3 maleimide [TQ3 maleimide]
TQ3 is designed to be a superior quencher to TAMRA, TF3 and Cy3. TQ3 has (a). much stronger absorption; (b). much higher quenching efficiency; and (c). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides.
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.

Enzo Life Sciences (6) TAMRA-12-ddUTP (25µl)
(6) TAMRA-12-ddUTP can be used for 3’-end labeling of oligodeoxynucleotides using terminal transferase. It also serves as a substrate for E. coli DNA Polymerase I (holoenzyme and Klenow fragment), T4 and T7 DNA polymerases, Taq DNA polymerase and reverse transcriptase. Oligonucleotide probes labeled with (6) TAMRA-12-ddUTP can be detected by direct fluorescence detection (orange fluorescence) or by methods using horseradish peroxidase- or alkaline phosphatase-linked anti-fluorescein antibodies. Alternative name: (6) TAMRA-12-2',3'-dideoxyuridine-5'-triphosphate. Concentration: 0.1mM. Purity: ≥93% (HPLC). Formulation: Liquid. Solution in water. Long Term Storage: -20°C. Excitation maximum: 552 nm. Emission maximum: 576 nm.
Enzo Life Sciences Fluorescein-5-maleimide (ultra pure) (25mg). CAS: 75350-46-8
Fluorescein-5-maleimide enables protein labeling via thiol modifications in most proteins at cysteine residues that either are intrinsically present or resulted from reduction of cystine residues. Unlike iodoacetamides, maleimides do not react with histidine and methionine under physiological conditions. The probe is suitable for assessing conformation- dependent accessibility of cysteine residues in proteins. Wavelength Maxima: Excitation 493nm, Emission 515nm Purity: ≥95% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.

Sartorius Incucyte Mouse IgG1
Incucyte Mouse IgG1 Fabfluor Antibody Labeling Dye is designed for quick easy labeling of Fc containing test antibodies with a green or red fluorophore. Once labeled the Fabfluor-antibody complex can be used for identification of surface expressed antigens in live cells. In the absence of expressed specific antigen little or no signal is seen on the cells.With the Incucyte integrated analysis software background fluorescence is minimized. This reagent has been validated for use with a number of different antibodies in a range of cell types.
