1 kb DNA Ladder in TE buffer
Descrition & Target
The 1 kb DNA Ladder is suitable for sizing linear double-stranded DNA fragments from 250 bp to 10 kb. The ladder is composed of chromatography-purified DNA fragments dissolved in TE buffer (10 mM Tris pH 7.5, 1 mM EDTA) at 100 ng/uL. The 1 kb, 3 kb, and 6 kb bands contain more DNA to provide internal orientation. The ladder is supplied with 1.5 mL of 6X Loading Buffer, which contains density agents and two blue electrophoresis tracking dyes that run at approximately 1.5 kb and 200 bp in a 1% agarose gel.

1,6-Dipheny-1,3,5-hexatriene
Descrition & Target
1,6-Diphenyl-1,3,5-hexatriene (DPH, excitation/emission=350 nm/420 nm) is almost non-fluorescent in water, but it exhibits a strong increase in fluorescence after intercalation into membranes and can be used as a probe for viscosity, polarity and lipid order. DPH has been used for the high-content imaging of neutral lipid droplets<sup>1</sup> as well as a reporter of inner spore membrane fluidity in bacterial spores<sup>2</sup>.
