BD Pharmingen™ Alexa Fluor® 647 Rat IgG2a, κ Isotype Control

Important Note: This pre-titered antibody solution does not contain a cell permeabilization agent. It is necessary to include a cell permeabilization agent when using the pre-titered antibody solution to stain fixed and permeabilized cells with Cytofix/Cytoperm  Kit(Cat. No. 554714). BD Perm/Wash™ Buffer (Cat. No 554723) contains the permeabilization agent saponin and is useful for this purpose as described in the USAGE section below.  

USAGE for Intracellular Staining

Resuspend 1 x 10e6 fixed and permeabilized cells in 5 µl of the pre-titered antibody solution and 45 µl of 1X Perm/Wash Buffer (Cat. No 554723).

Incubate the cell suspension for 15 minutes (at RT or 4°C).

Wash twice in 100 µl of 1X Perm/Wash Buffer (Cat. No 554723).

Bead-based compensation or unmixing controls, such as BD® CompBeads or BD™ SpectraComp™, can be used as surrogates to assess fluorescence spillover when bound to fluorochrome-conjugated antibodies. Although these beads have spectral properties similar to cells, variations in spectral emission may occur, resulting in differing spillover values compared to biological controls. Therefore, it is considered best practice to compare the spillover obtained from cells and bead-based controls when using BD® CompBeads or BD™ SpectraComp™ for the first time, to ensure they are appropriate for the intended application.

1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
5. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
7. An isotype control should be used at the same concentration as the antibody of interest.
