The easiest way to image your cellsMolecular Probes ReadyProbes reagents are ready-to-use imaging solutions designed to allow you to stain cells with:
|
Reach for the convenient dropper bottle, add 2 drops per milliliter of your cell suspension, and you're ready to image. ReadyProbes reagents address your most common imaging needs, including nuclear and cytoskeletal staining, and analyses for cell viability and apoptosis. In addition, we’ve formulated some of our most popular secondary antibodies for use straight from the dropper bottle. We’ve also developed ReadyProbes imaging accessories to help you get the best results from your staining protocol. Imaging has never been easier.
ReadyProbes Cell Stains
With each ReadyProbes reagent, you can follow the icon-based protocol to obtain quick and easy results for a common imaging application. ReadyProbes cell stains can remain on the bench within arm’s reach of your microscope. Add 2 drops per milliliter of solution, and you're ready for the next step in your experiment.

ReadyProbes Secondary Antibodies
ReadyProbes secondary antibodies are conjugated with bright and photostable Alexa Fluor™ 488 and Alexa Fluor594 dyes to offer convenient and robust labeling. These Alexa Fluor secondary antibodies recognize IgG heavy chains and all classes of immunoglobulin light chains from either mouse or rabbit. Like other ReadyProbes reagents, these secondary antibodies are provided in a convenient dropper bottle format. No pipetting or dilutions are required. Just add 2 drops per milliliter of buffer to stain your cells, and follow the icon-based protocol.
