Storage and Rehydration: Store freeze-dried solid at 2-8°C. Rehydrate with the indicated volume of dH2O and centrifuge if not clear. Prepare working dilution on day of use. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid.
Extended Storage after Rehydration: Aliquot and freeze at -70°C or below. Avoid repeated freezing and thawing. Alternatively, add an equal volume of glycerol (ACS grade or better) for a final concentration of 50%, and store at -20°C as a liquid.
Expiration date: one year from date of rehydration. The expiration date may be extended if test results are acceptable for the intended use.
Note: Store stained specimens at 4°C to preserve fluorescence.
BD Brilliant™ Violet 421 (BV421) has an Excitation peak at 407 nm with maximal emission at 421 nm. Brilliant Violet polymer chains can be considered as a collection of optical segments, each with the ability to absorb light and emit fluorescence signal. This results in materials that have a bright fluorescence signal for better resolution and sensitivity.
5-color imaging is possible with BV421, in combination with BV480, Alexa Fluor® 488, Rhodamine-Red™-X, and Alexa Fluor® 647. If nuclear counterstaining is desired, 4-color antibody staining is possible using Brilliant Violet™ 421, Brilliant Violet™ 480, Alexa Fluor® 488 and Rhodamine Red™-X. Switching the nuclear stain from DAPI (emission in the blue region) to DRAQ5™ (which has red emission) frees the violet-blue region of the spectrum to accommodate the two Brilliant Violet dyes. DRAQ5’s excitation and emission profiles overlap those of Alexa Fluor 647.
