Regulatory Status Legend
The FOXP2-73A/8 monoclonal antibody specifically binds to Forkhead box protein P2 (FoxP2). FoxP2 is also known as TNRC10 (Trinucleotide repeat-containing gene 10 protein), CAGH44 (CAG repeat protein 44), and SPCH1 (Speech and Language Disorder 1). FoxP2 is a member of the forkhead/winged-helix (FOX) family of transcription factors. Normal FOXP2 gene expression is associated with the proper development of cardiovascular, gastrointestinal, and neural tissues including the speech and language regions of the brain. FoxP2 protein has been detected in most normal tissues including epithelial and endothelial cells but not cells of hematopoietic origin. Although not normally detected in lymphocytes and plasma cells, FoxP2 protein was reportedly expressed in a small fraction of plasma cells from reactive human tonsils. Aberrant FOXP2 gene expression has been associated with abnormal plasma cell generation and may play a role in multiple myeloma and other hematological malignancies. The FOXP2-73A/8 antibody detects human and mouse FoxP2 and does not crossreact with other members of the FOXP family (FoxP1, FoxP3 or FoxP4).
Alexa Fluor® 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor® 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
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.
- 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.
- An isotype control should be used at the same concentration as the antibody of interest.
- The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.

- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- 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.
