Molecular Probes® Protein Labeling Kits provide a convenient means for attaching a fluorescent label (or biotin) to an antibody (or a protein larger than 40 kDa). Conjugates are ideal for multiple applications, including flow cytometry, fluorescent microscopy, immunohistochemistry, primary detection, ELISAs, immunocytochemistry, FISH, and more. Kits are available in 12 Alexa Fluor® dye colors, biotin, the hapten Oregon Green® 488, fluorescein EX, and Texas Red® dye. Each kit provides the components needed to perform three protein conjugations and purifications. Important Features of Protein La...

Zenon® labeling technology provides a fast, versatile, and reliable method for adding a fluorescent label to an antibody. You need only a small amount of starting material,and the method is optimized for efficient labeling of antibodies in serum, ascites fluid, or hybridoma suspensions. Antibody conjugates formed using Zenon® technology may be used in protocols where a directly labeled primary antibody is suitable, including flow cytometry, imaging, and high-throughput applications. This exclusive Molecular Probes® Zenon® labeling technology greatly simplifies the use of multiple mouse-derived...

This single 5-isomer preparation of our proprietary, amine-reactive dye, Oregon Green 488 carboxylic acid, succinimidyl ester and its conjugates have green fluorescence similar to that of fluorescein but are more photostable. Additionally, Oregon Green 488 dye has a lower pK a than fluorescein (pK a = 4.7 versus 6.4 for fluorescein), making this bright dye less pH sensitive in the physiological range.

The Click-iT® HPG Alexa Fluor® 488 Protein Synthesis Assay Kit provides a fast, sensitive, non-toxic, and non-radioactive method for the detection of nascent protein synthesis utilizing fluorescence microscopy, high-content imaging, or flow cytometry. Included in the kit are L-homopropargylglycine (HPG), an amino acid analog of methionine containing an alkyne moiety, and Alexa Fluor® 488 azide. The HPG is fed to cultured cells and incorporated into proteins during active protein synthesis. Addition of the Alexa Fluor® 488 azide leads to a chemoselective ligation or "click" reaction between the...
