Biotium Products & Reviews

Cell membrane-impermeant, nuclear-specific counterstains. Suitable for fixed cells or staining dead cells in live cultures. Available in a variety of colors from green to near-infrared (near-IR).

A laser diode-based gel illuminator for visualizing fluorescent nucleic acid and protein gels. Avoids UV light hazards and offers exceptional performance for widely used green and red dyes.

A qPCR master mix containing Evagreen qPCR dye and Cheetah™ Taq hotstart DNA polymerase, suitable for qPCR using a fast cycling protocol.                  

A magnetic bead-based kit for superior DNA extraction from FFPE samples. Features proprietary technology for enhanced removal of formaldehyde-induced damage, providing DNA with higher yield and greater amplifiability.

Highly sensitive, fluorescence-based quantitation of purified proteins.

A ready-to-use luminescent protein gel stain optimized for UV-based fluorescence imaging systems. Non-toxic, with no fixation required.

Live cell bacteria stains, suitable for flow cytometry or fluorescence microscopy. Stain live and dead, gram-positive and gram-negative bacteria with green or red fluorescence.

Fluorogenic mitochondrial stains for live cells that rapidly accumulate in mitochondria and can be imaged without washing.

Ultrapure molecular biology grade agarose pre-coated with GelRed® Nucleic Acid Gel Stain for convenient and safer preparation of precast gels.

The most sensitive RNA gel stain available in convenient pre-coated agarose format. Includes formamide-containing RNA loading dye.

An RNA-selective, fluorescent RNA quantitation kit with the widest linear range (5 ng–1000 ng RNA) of any RNA quantitation assay. Designed for use in a microplate reader or a Qubit® fluorometer.

Novel lipophilic fluorescent dyes for selective staining of the plasma membrane in formaldehyde-fixed cells. Available in 6 colors, from blue to near-IR.

Dye solutions of lipophilic carbocyanine dyes DiB, Neuro-DiO, DiI, and DiD, as well as novel near-infrared lipophilic dyes for non-toxic labeling of cytoplasmic membranes.

Unique fluorogenic membrane dyes that covalently stain the plasma membrane in live cells, and can withstand both fixation and detergent permeabilization.

A patented green fluorescent nucleic acid dye with features that are ideal for applications such as qPCR, HRM®, LAMP, and digital PCR.

Kit includes each of ExoBrite™ 490/515 EV Surface Stains (CTB, WGA, and Annexin V) for assessing which stain offers the best coverage for EV samples of interest.

A high-throughput fluorescence-based assay for protein stability screening with higher tolerance for detergents and other protein additives compared to commonly used Thermal Shift dyes.

A two-color viability staining kit optimized specifically for gram-positive bacteria strains. Offers a simple 30-minute staining protocol, no wash required.

Fluorescent Annexin V conjugates that are optimized for bright and low background staining of extracellular vesicles for flow cytometry.
