Biotium Life Sciences 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).

GelRed ® is an ultra sensitive, extremely stable and environmentally safe fluorescent nucleic acid dye designed to replace the highly toxic ethidium bromide (EB) for staining dsDNA, ssDNA or RNA in agarose gels or polyacrylamide gels. GelRed ® is far more sensitive than EB without requiring a destaining step.

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.                  

Kits for reversible protein visualization and quantitation on protein gels and western blot membranes by labeling with near-infrared CF® dyes.

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.

TyraMax™ Amplification Dyes for 3-plex tyramide signal amplification (TSA), plus DAPI. Includes TyraMax™ 490/520 (green fluorescence), TyraMax™ 560/580 (red fluorescence), TyraMax™630/650 (far-red fluorescence). One vial of each TyraMax™ Dye (100 uL, 100X) and one vial of DAPI (50 uL, 1000X).

Set of TyraMax™ Amplification Dyes for 5-plex tyramide (TSA) staining with DAPI. TyraMax™ 490/520 (green), TyraMax™ 560/580 (red), TyraMax™630/650 (far-red), TyraMax™ 680/700 (far-red/NIR), TyraMax™ 740/770 (near-IR). One vial of each TyraMax™ Dye (100 uL, 100X), and one vial of DAPI (50 uL, 1000X).

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.

Set of TyraMax™ Amplification Dyes for multiplex tyramide signal amplification (TSA) assay development, with multiple unique dye options spanning UV to near-IR wavelengths. Inculdes 12 dye vials, 20 uL of each 100X TyraMax™ dye option.

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.

A fluorescent dsDNA quantitation kit with a wide linear range of 0.03-250 ng DNA. Designed for use in a fluorescence microplate reader.
