CD151 Mouse anti-Human, Brilliant Violet 421, Clone: 14A2.H1, BD Optibuild™

Description

• Reacts with platelet-endothelial cell tetraspan antigen-3 (PETA-3), a 27 kD membrane glycoprotein, expressed on platelets, megakaryocytes, lymphocytes (weak), monocytes, endothelial cells and epithelial cells
• PETA-3 (CD151) associates withβ1 integrin in certain tissues
• This has also been shown with other tetraspan superfamily members, like CD9, CD63 andα5β1
• Reports indicate that this association or colocalization of CD151 withβ1 integrin in tissues suggests a functional role of this molecule, however, this role has not been elucidated yet
• It has also been reported that antibody 14A2.H1 is capable of platelet activation in vitro.Studies showed that different clones of CD151 monoclonal antibodies display strikingly different patterns of binding to human haemopoietic cells and tissue sections, and that this is due at least in part to the presence of the protein in complexes with different integrins
• The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes
• With an Ex Max of 407nm and Em Max at 421nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50nm filter)
• BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates
• BV421 is a polymer-based dye excited by the violet laser and is one of the brightest fluorochromes offered by BD Biosciences
• Conjugates are typically 10 times brighter than Pacific Blue™ conjugates and are often as bright as or brighter than PE conjugates
• Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue™, and BD Horizon™ V450 cannot be used simultaneously.
