BD Horizon™ Brilliant Stain Buffer
(RUO)
Description
The BD Horizon™ Brilliant Stain Buffer is a buffer for the immunofluorescent staining of cells. Brilliant Stain Buffer is a solution that is added to mixtures of certain fluorescent reagents before staining cells. It was designed to complement multicolor flow cytometry experiments that utilize two or more different staining reagents conjugated with BD Horizon Brilliant fluorescent polymer dyes. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment. When using only one BD Horizon Brilliant reagent in an experiment, the Brilliant Stain Buffer is not needed. The BD Horizon Brilliant Stain Buffer is compatible with the use of other fluorescent staining reagents conjugated with traditional fluorochromes, such as fluorescein, phycoerythrin or Alexa Fluor® dyes.
Preparation And Storage
Recommended Assay Procedures
Protocols for Multicolor Immunofluorescent Staining of Cells Using BD Horizon Brilliant Stain Buffer
Multicolor Staining of Human Cell Samples in Tubes or 96-Well Plates Using Individual Staining Reagents
1. Add 50 μL of BD Horizon Brilliant Stain Buffer to all tubes or desired wells for the experiment
Note: The 50 μ L amount of Brilliant Stain Buffer per tube or per well does not depend on the final staining volume or amount of cells used per tube or number of BD fluorescent antibodies used in staining. Although written for use with human cells, these protocols can readily be adapted for analyzing mouse cells or cells from other species, for example, by staining mouse cells at 4°C rather than at room temperature (RT).
2. Add each fluorescent reagent at the recommended volume per test (eg, 5 μL or 20 μL) and then proceed to either Protocol 1, 2, or 3.
Protocol 1 for Staining Whole Blood Samples in Tubes
a. Add 100 μL of human whole blood to each tube
b. Vortex tube contents
c. Incubate (30 min) the suspended cells protected from light at room temperature (RT)
d. Add 2 mL of BD FACS™ Lysing Solution (Cat. No. 349202; 10 min) or BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899; 15 min) per tube and incubate protected from light at RT
e. Pellet cells by centrifugation (5 min) at 1400-1500 rpm
f. Aspirate supernatant; add 2-3 mL of stain/wash buffer, eg, BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656)
or BD Pharmingen™ Stain Buffer (BSA) (Cat. No. 554657)
g. Pellet cells by centrifugation (5 min) at 1400-1500 rpm
h. Aspirate the supernatant and resuspend cells in 500 μL of stain/wash buffer for flow cytometric analysis
Protocol 2 for Staining Peripheral Blood Mononuclear Cells or Bulk Erythrocyte-lysed Whole Blood Samples in Tubes
a. Add 100 μL of human cells to eac h tube
b. Vortex tube contents
c. Incubate (30 min) the suspended cells protected from light at room temperature (RT)
d. Add 2 ml of stain/wash buffer per tube
e. Pellet cells by centrifugation (5 min) at 1400-1500 rpm
f. Aspirate supernatant; add 2-3 mL of stain/wash buffer
g. Pellet cells by centrifugation (5 min) at 1400-1500 rpm
h. Aspirate the supernatant and resuspend cells in 500 μL of stain/wash buffer for flow cytometric analysis
Protocol 3 for Staining Peripheral Blood Mononuclear Cells or Bulk Erythrocyte-lysed Whole Blood Samples in 96-well Plates
Note: When planning for staining in plates, the user must account for the volume of the BD Horizon Brilliant Stain Buffer used. Although written for use with human cells, this 96-well plate-based protocol can readily be adapted for analyzing mouse cells or cells from other species.
a. Add 50 μL of human cells to each well
b. Incubate (30 min) protected from light at RT
c. Wash by adding 100 μL of stain/wash buffer
d. Pellet cells by centrifugation (5 min) at 1400-1500 rpm
e. Aspirate supernatants
f. Resuspend pelleted cells by adding 250 μL of stain/wash buffer
g. Pellet cells by centrifugation (5 min) at 1400-1500 rpm
h. Aspirate supernatants
i. Resuspend pelleted cells thoroughly with 150 μL stain/wash buffer by pipetting the suspended cells several times
j. Transfer well contents to tubes and add additional stain/wash buffer to the tubes as desired for flow cytometric analysis
Note: Alternatively, acquire samples for flow cytometric analysis from the plate directly
Multicolor Staining of Human Cell Samples in Tubes or 96-Well Plates Using Cocktailed Staining Reagents
Instead of adding staining reagents individually to each tube or well of a 96-well plate, it may be desirable to add cocktailed staining reagents, ie, mixtures of two or more fluorescent staining reagents. The following protocol provides an example of how to prepare a “per test” 5-Color Fluorescent Antibody Cocktail that already contains BD Horizon Brilliant Stain Buffer.
Human Samples: Pre-mixed Fluorescent Reagent Cocktails
For each multicolor test of cocktailed fluorescent reagents:
i) Add 50 μL of BD Horizon Brilliant Stain Buffer per test
ii) Add each fluorescent reagent at the recommended volume per test (5 μL or 20 μL)
iii) Mix reagents (especially after adding BD Horizon Brilliant reagents)
iv) Store cocktail at 4°C protected from light if it is to be used later
Note: Protected from light, fluorescent reagent cocktails containing more than one Brilliant Violet and/or Brilliant Blue reagent are best used within 24 hours after preparation when stored at 4ºC or within 4 hours when stored at room temperature. However, when more than one Brilliant Ultraviolet (BUV) reagent is in the cocktail, it is best used within 2 hours after preparation irrespective of storage temperature.
Example of creating a 5-Color Fluorescent Antibody Cocktail containing 2 different Brilliant Violet™ Conjugates
Final Volume per Test = 90 μL

Compensation and Setup
BD Horizon Brilliant Stain Buffer can be used in single color compensation controls using cells. The buffer is compatible with BD™ Compbeads, however, it has not been tested with compensation beads from other vendors.
