Regulatory Status Legend
The W5C5 monoclonal antibody specifically reacts with SUSD2 (sushi domain containing 2), which is expressed on mesenchymal stem cells (MSC) and on some cancers and neoplastic cell lines. It is not detected on hematopoietic cells of the peripheral blood and bone marrow. SUSD2 is a type I transmembrane protein that may interact with galectin-1 and the potential cytokine C10orf99, through which it may affect cell growth and immune responsiveness. It has a large extracellular region that contains a sushi domain (a conserved sequence that is often associated with proteins of the complement system). SUSD2 is a marker that is useful for identifying and isolating MSC from bone marrow and endometrial tissue, and those MSC may be induced to differentiate into a wide variety of cell types. Varying levels of SUSD2 expression may correlate with either suppression or enhancement of the growth of different types of neoplastic cells, presumably via a variety of direct and indirect mechanisms.
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.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
