Fluorescence Microscopy

Thiazole red homodimer (TRhD), also known as TOTO®-3, is a cell-impermeant, high-affinity, far-red fluorogenic nucleic acid stain.

TO Iodide, also known as TO-PRO®-1, is a green fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

Cell surface staining kits with fluorescent membrane dye plus enhancer for imaging live cell surface for several hours to days.

Novel lipophilic fluorescent dyes for selective staining of the plasma membrane in formaldehyde-fixed cells. Available in 5 colors, from blue to near-IR.

DAPI is a popular blue fluorescent DNA dye. The dye binds to the minor groove of dsDNA with approximately 20-fold fluorescence enhancement.

A high purity grade, red fluorescent nucleic acid dye for detecting nucleic acids in solution or for selectively staining dead cells with damaged plasma membranes.

Unique hardset antifade that quenches lipofuscin autofluorescence. Choose with mounting medium with DAPI, far-red NucSpot® 640, or without nuclear stain.

Biotium’s hardset antifade mounting medium with NucSpot® 640 far-red nuclear counterstain.

Oxazole Blue, also known as PO-PRO™-1, is a blue-fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

A highly selective actin filament stain for fixed and permeabilized cells. Labeled phalloidins have similar affinity for both large and small filaments.

For simple, optimized tyramide amplification of immunostaining in cells or tissue sections. No need to add hydrogen peroxide before use.

Quench lipofuscin autofluorescence in PBS, with minimal background.

An optimized buffer with enhanced sensitivity for tyramide signal amplification of immunostaining in cells or tissue sections.

10-Acetyl-3,7-dihydroxyphenoxazine (Amplex® Red), is regarded as the best fluorogenic substrate for peroxidase and H₂O₂ because it is highly sensitive, specific and stable.

7-AAD (7-aminoactinomycin D) is a membrane-impermeant fluorescent DNA binding dye that is useful for live/dead discrimination and cell cycle profiling by flow cytometry.

Biotin-XX tyramide conjugate can be used for tyramide signal amplification (TSA) to generate high-density labeling of a target protein or nucleic acid with biotin.
