Annexin V fluorescent conjugates can be used to detect apoptotic cells. Annexin V is available labeled with our superior near-IR fluorescent dyes.

This kit contains everything you need to label antibodies or other proteins with a fluorescent CF® dye succinimidyl ester (CF® dye SE) or biotin succinimidyl ester (biotin SE). Each kit contains reagents for three labeling reactions of up to 1 mg protein per reaction.

CF® Dye Amines can be used to conjugate CF® dyes to carboxylic acids groups in biological molecules.

CF® Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues.

CF® Dye Maleimides are thiol-reactive fluorescent dyes. Maleimides are commonly used to label proteins on free thiol groups.

Mix-n-Stain™ antibody labeling kits are a revolutionary antibody labeling technology that allows you to label your antibody with one of our superior CF® dyes in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. Now with an extended shelf life of at least 1 year.

Near-IR CF® dye free acids are control dyes for studies that involve CF® dye succinimidyl ester conjugated to antibody, protein or peptides.  Available with the following CF® dyes: CF®680, CF®750, CF®770, and CF®790.

This labeling kit comprises our superior near-IR amine-reactive CF® dye and other components necessary for carrying out antibody labeling and purification. It’s available with the following CF® dyes: CF®680, CF®750, CF®770, and CF®790.

This product is concanavalin A (Con A) labeled with our superior fluorescent CF® dyes. Con A is a widely used lectin that selectively binds to a-mannopyranosyl and a-glucopyranosy residues, found in the cell wall of yeast and fungi, and the cell membrane of mammalian cells.

This product is prepared by labeling highly cross-adsorbed donkey anti-goat IgG (H+L) with a selection of our bright and photostable CF® dyes and other labels. To minimize cross-reactivity, the antibody has been adsorbed against chicken, guinea pig, Syrian hamster, horse, human, mouse, rabbit, and rat serum.

This product is prepared by labeling highly cross-adsorbed donkey anti-rabbit IgG (H+L) with our bright and photostable CF® dyes. To minimize cross-reactivity, the antibody has been adsorbed against  bovine, chicken, goat, guinea pig, Syrian hamster, horse, human, mouse, rat, and sheep serum.

This product is prepared by labeling high quality goat anti-mouse IgG (H+L) with a selection of our bright and photostable CF® dyes and other labels.

CF® dye goat anti-mouse IgG2b isotype-specific secondary antibody conjugates are labeled with our exceptionally bright, photostable CF® dyes. The conjugates are prepared from affinity-purified antibodies that react with Fc portion of the heavy chain of mouse IgG2b. To minimize cross reactivity, the antibodies are cross-adsorbed against other mouse IgG subclasses (IgG1, IgG2a, IgG3), and human, bovine and rabbit serum proteins.

CF®750 goat anti-mouse IgG isotype-specific secondary antibody conjugate is prepared from affinity-purified antibodies that react with Fc portion of the heavy chain of mouse IgG3. To minimize cross reactivity, the antibodies are cross-adsorbed against other mouse IgG subclasses (IgG1, IgG2a, IgG2b, IgG2c), and human, bovine and rabbit serum proteins.

This product is prepared by labeling high quality goat anti-rabbit IgG (H+L) with a selection of our bright and photostable CF® dyes and other labels.

Transferrin is a glycoprotein with homologous N-terminal and C-terminal iron-binding domains that binds up to two Fe(III) atoms for delivery to vertebrate cells through receptor-mediated endocytosis.
