The advantages of multi-colour staining are well-known and manufacturers of protein research tools and services are constantly providing users with a broader selection of colour variants. Abcam has added new Alexa Fluor 405/568/750 conjugated antibodies to its existing 488/555/594/647 conjugates in the same product range, which provides bright staining and low background. The portfolio comprises antibodies raised against mouse/rabbit/rat/chicken/goat/sheep/guinea pig IgG and against mouse/rabbit IgM. It also includes a selection of pre-adsorbed/cross-adsorbed and F(ab’)2 fragment secondaries to ensure low species cross-reactivity. A dilution range of 1/200-1/1,000 in IF/ICC allows for at least 250 stainings per product to improve cost efficiency. Abcam Plc
