Products & Reviews

A fluorescent dsDNA quantitation kit with a linear range of 1-3,000 pg DNA, an unprecedented level of sensitivity in dsDNA detection. Designed for use in a fluorescence microplate reader.

Kits to covalently label dead cells, allowing cells with permeable plasma membranes to be excluded from analysis in flow cytometry. A wide variety of dye options for standard flow, spectral flow, and fluorescence microscopy.

Cell-permeant probes for imaging the microtubule cytoskeleton in live cells. Available with blue, green, or far-red fluorescence.

Annexin V fluorescent conjugates can be used to detect apoptotic cells. Annexin V is available conjugated to a wide variety of dyes.

Ultra sensitive and environmentally safe replacement for EtBr DNA/RNA gel stain.

A luciferase-based ATP cell viability assay offering high sensitivity, wide dynamic range, and long-lasting signal for high-throughput luminescence detection in microplates.

Fluorescent dyes optimized for staining endospores. The dyes also stain both live and dead bacteria of gram-positive and gram-negative strains. In B. subtilis, the dyes stain both vegetative cells and endospores and have been validated for detection by fluorescence microscopy and flow cytometry.

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

Easily label SNAP-tag®, CLIP-tag™, HaloTag®, or other ligands with fluorescent dyes, no purification needed. Cell membrane-permeant and impermeant dye options for intracellular or surface targets.

A fluorescent dsDNA quantitation kit with a linear range of 2-2000 ng DNA. Designed for use in a fluorescence microplate reader.

The most sensitive DNA gel stain available in convenient pre-coated agarose format with no need for post-electrophoresis staining.

Highly-selective dead cell stains for bacteria cultures. The stains are suitable for both gram-positive and gram-negative strains.

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

Label 5-50 ug of VHH (also known as Nanobodies®) containing a single free cysteine with Biotium’s bright and photostable CF® Dyes, with no purification after labeling.

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

Superior DNA extraction from FFPE samples, due to the enhanced removal of formaldehyde-induced damage, providing DNA with higher yield and quality and greater amplifiability.

Superior RNA extraction from FFPE (paraffin) tissue sections with 3 to 30-fold increase in yield, and 2-fold increase in DV200 (RNA longer than 200 nucleotides) compared to other methods.

A combination kit for dual extraction of DNA and RNA from a single FFPE sample, featuring proprietary CAT5™ technology.

Kits for increasing immunofluorescence sensitivity using HRP-catalyzed tyramide signal amplification; with your choice of next-generation fluorescent CF® dyes or biotin.

LipidSpot™ dyes rapidly stain lipid droplets in live cells or fixed cells, with no wash step required. Available with green or red/far-red fluorescence.

Fluorescent WGA conjugates that are optimized for bright staining of extracellular vesicles for flow cytometry.

Wet-set antifade mounting medium for preserving fluorescence of our CF® dyes and other fluorochromes, in a dropper bottle for easy dispensing.

The CF® dye TUNEL Assay Apoptosis Detection Kit label apoptotic cells in fixed tissue sections or cellular samples for fluorescence microscopy or flow cytometry.

Optimized and easy-to-use kit for extracting total RNA, including mRNA and miRNA, from purified EVs for downstream analysis in qPCR or RNAseq.

EvaGreen® Plus Dye has an improved signal-to-noise compared to original EvaGreen® dye, for higher sensitivity in DNA amplification applications.
