货品编号： Invitrogen.S11224 品牌： Invitrogen 品名： Streptavidin, Alexa Fluor 532 conjugate 规格： 1mg

产品描述：

Alexa Fluor® 532 streptavidin comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (Alexa Fluor® dye).

Streptavidin has a very high binding affinity for biotin, and a conjugate of streptavidin is commonly used together with a conjugate of biotin for

specific detection of a variety of proteins, protein motifs, nucleic acids, and other molecules (for example, a biotinylated primary antibody bound

to a protein target can be detected with a fluorescently labeled streptavidin). Strategies similar to this are used in many detection protocols

including western blots, flow cytometry, imaging and microscopy, and microplate assays. Alexa Fluor® dye streptavidin conjugates are supplied

as 1 mg lyophilized product or in 0.5 mL volumes of a 2 mg/mL solution.

Important Features of Alexa Fluor® 532 Streptavidin Conjugates: • Alexa Fluor® 532 streptavidin conjugate has Ex/Em maxima of ~ (530/554) • Bright, photostable fluorescence • High solubility in aqueous solutions • Available in multiple colors •Ideal for western blots, flow cytometry, imaging and microscopy, microplate assays and more
