Sistemi di associazione e marcatura delle proteine

Protein linking and labelling systems provide a convenient means for attaching fluorescent labels or biotins to antibodies and larger proteins. These kits are ideal for use with multiple applications, including flow cytometry, fluorescent microscopy, immunohistochemistry, primary detection, ELISAs, immunocytochemistry, and FISH. These systems are available with a variety of dye colours, biotin, fluorescent agents, and all the components needed to perform multiple conjugations and purifications. Protein labelling follows a simple protocol of reaction, separation, and then use.

CF™ dye bovine serum albumin conjugates

Supplier: Biotium

Fluorescent bovine serum albumin (BSA) conjugates are commonly used as tracers in applications where physical dimensions are important. The conjugates can also be used for quantitative studies of electroporation, measurement of plasma volume in rats, and endocytosis studies. CF™ dye BSA conjugates are labelled with fluorescent CF™ dyes, which offer advantages in brightness and photostability compared to other fluorescent dyes.
