Regulatory Status Legend
The S2-647 monoclonal antibody recognizes the Von Hippel-Lindau (VHL) protein. The VHL protein is expressed within the cytosol and nuclei of cells from a variety of tissues. It serves as a tumor suppressor and transcriptional repressor that is highly conserved from Drosophila to mammalian species. VHL binds to Elongin B and C subunits and other proteins as part of a E3 ubiquitin ligase complex that targets a variety of proteins, including HIF-1 alpha and Beta-2 adrenergic receptors, for proteasomal degradation. Aberrant VHL expression is associated with a number of diseases including Von Hippel-Lindau disease, a familial cancer syndrome, that predisposes individuals to hemangioblastomas of the central nervous system and retina, pheochromocytoma and renal cell carcinoma. Three distinct VHL isoforms ranging in molecular weight from approximately 19-30 kDa have been described.
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.

- 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).
- 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).
- 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.
