Obtain superior images with the new Invitrogen™ Alexa Fluor™ Plus secondary antibodies. Make your low abundant targets visible, minimize time spent optimizing, and make your precious samples count. Alexa Fluor™ Plus secondary antibodies provide brighter signal while having lower cross-reactivity compared to leading Alexa Fluor secondary antibodies, providing you with higher sensitivity and better signal-to-noise for your critical experiments. Alexa Fluor Plus secondary antibodies represent an advancement in fluorescent conjugate technology. Alexa Fluor Plus secondary antibodies are conjugated using new, proprietary dye chemistry and are pre-adsorbed to reduce background and cross-reactivity so you can generate stunning images. Alexa Fluor Plus secondary antibodies provide up to 4.2 fold higher signal-to-background in imaging applications and up to 5.8 fold higher signal-to-background in fluorescent western applications compared to Alexa Fluor secondary conjugates.
