CD104 Rat anti-Human, Brilliant Violet 711, Clone: 439-9B, BD Optibuild™

Description

• The 439-9B monoclonal antibody specifically recognizes CD104, integrinβ4 chain, a 205 kDa transmembrane glycoprotein, which associates with CD49f (integrinα6 chain) to form theα6/β4 (CD49f/CD104) complex
• It is expressed on epithelial cells, Schwann cells, and some tumor cells
• The CD49f/CD104 complex is located in the hemidesmosomes of the epidermis, suggesting its role in epidermal cell-basement membrane adhesion
• The clone 439-9B was clustered as CD104 at the fifth Human Leucocyte Differentiation Antigen International Workshop
• It may be used for immunoprecipitation, immunoblotting and immunohistochemistry on frozen tissue sections
• The antibody was conjugated to BD Horizon™ BV711 which is part of the BD Horizon Brilliant™ Violet family of dyes
• This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405nm and an acceptor dye with an Em Max at 711nm
• BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor™ 700-like dyes (eg, 712/20nm filter)
• Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor™ 700 and PerCP-Cy5.5 detectors
• However, the spillover can be corrected through compensation as with any other dye combination
• BV711 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an emission maximum at 711 nm
• This dye offers a very bright choice for the violet laser
• Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor™ 700 and PerCP-Cy5.5 detectors
• BV711 will also have moderate spillover into the BD Horizon Brilliant™ Violet 786 detector.
