Create a perfectly labeled antibody with the SiteClick™ Qdot® 705 Antibody Labeling Kit. This kit replaces the conventional Qdot® 705 Antibody Conjugation Kit (Q22061MP). Unlike the conventional amine-thiol crosslinker method, SiteClick™ labeling specifically attaches the label to the heavy chains of an IgG antibody, ensuring that the antigen-binding domains remain available for binding to your antigen target. This site selectivity is achieved by targeting the carbohydrate domains present on essentially all IgG antibodies regardless of isotype and host species. In addition, no harsh reduction steps are required, and the labeling is consistent and reproducible each time it is performed. Depending upon the label, the resulting SiteClick™ -labeled antibody can be used in flow cytometry, fluorescence imaging, or Western blot detection.

Important Features of the SiteClick™ Qdot® 705 Antibody Labeling Kit:

• Contains everything required to label 100 µg of IgG antibody
• Easy to follow step-by-step protocol
• Highly efficient, site-specific, reproducible labeling chemistry results in high quality antibody conjugate.
• Qdot® 705 labels can be used in confocal or traditional fluorescence microscopy.
• In flow cytometry, Qdot® 705 can be excited by the 488 nm line of the argon-ion laser, or alternatively via excitation at 405 nm. This is true of all Qdot® fluorophores.

Qdot® Fluorophores are Our Brightest Labels
Antibody conjugates made with Qdot® fluorophores produce fluorescence output that surpasses that of traditional organic dyes. Paired with the correct optical filters, Qdot® nanocrystals are as much as 50 times brighter. Read more about Qdot® nanocrystals or review additional product details in Qdot® Nanocrystals—Section 6.6 in the Molecular Probes® Handbook.

Learn More About Protein and Antibody Labeling
We offer a wide selection of Molecular Probes® antibody and protein labeling kits (see Antibody Labeling from A to Z). To learn more about our various kits, read Kits for Labeling Proteins and Nucleic Acids—Section 1.2 in the Molecular Probes® Handbook.

Custom SiteClick™ Antibody Labeling Services
If you have an antibody that is considered "difficult to label" or has lost activity after labeling using a conventional method, please contact our custom service representatives to determine whether the SiteClick™ Antibody Labeling Service would be right for your antibody. We offer complete custom SiteClick™ antibody labeling services with the option of multiple detection molecules including biotin, Alexa Fluor® dyes, Qdot® fluorophores, R-PE, and others.
