BD, 557865, BD Pharmingen™ Alexa Fluor® 647 Rat IgG1, κ Isotype Control

Isotype: Rat IgG1, κ
Immunogen: Mouse immunoglobulin
Application: Intracellular staining (flow cytometry), Isotype control (Routinely Tested)
Vol. Per Test: 5 µl
RRID: AB_396908
Storage Buffer: Aqueous buffered solution containing BSA and ≤0.09% sodium azide.
Regulatory Status: RUO
Preparation And Storage: Preparation And Storage The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
Recommended Assay Procedures: Recommended Assay Procedures Immunofluorescent Staining for Intracellular Cytokines: The FITC-, PE-, APC-, PE-Cy7-, Alexa Fluor® 488- and Alexa Fluor® 647-conjugated-R3-34 immunoglobulin (Cat. No. 554684, 554685, 554686, 557645, 557856, and 557865) is a suitable rat IgG1 isotype control for assessing the level of background staining on paraformaldehyde-fixed/saponin-permeabilized mouse or human cells for flow cytometric analysis. The intracellular cytokine staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe.
Product Notices: Product Notices 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). Since applications vary, each investigator should titrate the reagent to obtain optimal results. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC). For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors. Source of all serum proteins is from USDA inspected abattoirs located in the United States. 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.
