Supplier: Biotium

A wheat germ agglutinin (WGA) lectin labelled with Biotium’s CF® Dyes or HRP. It is a carbohydrate-binding lectin that has high affinity for sialic acid and N-acetylglucosamine moieties of glycoproteins. As a result, WGA conjugates will label yeast bud scars and the cell membrane of gram-positive bacteria and mammalian cells.

EverBrite™ mounting media are anti-fade mountants for preserving fluorescence during microscopy. EverBrite™ mounting media prevent rapid photobleaching of fluorescein, rhodamine, and cyanine based dyes and are optimally formulated for use with Biotum’s CF™ dye conjugates. Unlike Vectashield® EverBrite™ mounting media is compatible with Cy® dyes such as Cy®2, Cy®3 and Cy®5. EverBrite™ mounting medium is a wet-set medium while EverBrite™ hardset mounting medium cures overnight to form a hard permanent seal with the coverslip, eliminating the need to seal coverslip edges with nail polish or other sealants. Both formulations are available with DAPI for blue fluorescent nuclear counterstaining without an additional staining step.

AccuGreen™ kit is specific for dsDNA and can quantify DNA samples in the range of 0,1 to 10 ng/μl.

Supplier: Biotium

PMA (propidium monoazide) dye is a DNA modifier invented by scientists at Biotium. It is a photo-reactive dye that binds to dsDNA with high affinity. Upon photolysis with visible light, PMA dye covalently attaches itself to dsDNA.

Supplier: Biotium

TrueBlack™ is a reagent for quenching lipofuscin autofluorescence in tissue sections for immunofluorescence staining. Lipofuscin consists of highly autofluorescent granules of oxidized proteins and lipids that build up in the lysosomes of aging cells. Lipofuscin granules fluoresce brightly in all channels used for fluorescence microscopy and accumulate in a cell and tissue types with age.

Supplier: Biotium

Thiazole green, which is structurally identical to SYBR® green I nucleic acid gel stain, is one of the most sensitive stains available for detecting double-stranded DNA (dsDNA) in agarose, polyacrylamide gels and qPCR.

Supplier: Biotium

Propidium iodide (PI) is a membrane-impermeant nucleic acid intercalator. The dye is commonly used to selectively stain dead cells in a cell population and also used as a counterstain in multicolor fluorescent imaging.

Supplier: Biotium

PMAxx™ dye is a DNA modifier used for viability PCR (v-PCR). V-PCR is a powerful PCR-based, culture-independent, method for rapid and sensitive quantification of microbial viability.

Supplier: Biotium

The Super HT PAP pen draws a water repellent circle around slide mounted tissue and prevents the waste of valuable reagents by keeping the liquid pooled in a single droplet. The regular sized super HT PAP pen can be used in about 800 applications, while the mini sized super HT PAP Pen will last about 400 applications.

Supplier: Biotium

MTT, XTT, and resazurin are reduced by mitochondrial metabolic activity to yield coloured or fluorescent products, and thus are useful for and assaying cell viability and quantitating cell number. MTT and XTT are reduced to coloured formazin salts that can be measured by absorbance. MTT generates an insoluble formazin salt, requiring cell lysis before the absorbance can be measured, while XTT does not require cell lysis for measurement. Resazurin is a non-fluorescent blue dye that is reduced to the pink fluorescent compound resorufin, which can be measured by fluorescence or absorbance.
