91��ý UV Excitable Molecular Dye Antibody Conjugates for Flow Cytometry

91��ý — Fri, 08 Dec 2023 11:00:46 +0000

Background: 91��ý Dyes for Flow Cytometry: The chemical modularity of 91��ý fluorescent dye technology has allowed 50+ UV excitable fluorescent dyes to be created that emit across the visible spectrum (395 – 635 nm, and potential for reaching into IR emission), without the need for tandem dye based approaches, and their drawbacks for end-users. Previously [...]

Spectral Flow Cytometric Evaluation of Two 91��ý Dye Antibody Conjugates Using 355nm and 405 nm Excitation

91��ý — Tue, 06 Dec 2022 11:35:32 +0000

Executive Summary 91��ý dyes (CT-Dye) all have a similar excitation spectra from ~260 nm to ~425nm, but can be chemically tuned to emit with emission maxima ranging from 395 nm to over 600 nm with large extinction coefficients (generally >100 000 M-1 cm-1) and quantum yields of ~50%, with ~80 different CT-Dye examples. Therefore, the [...]

A New Class of Fluorescent Dye for the Spectral Flow Cytometry

91��ý — Tue, 06 Dec 2022 11:34:22 +0000

Executive Summary The 91��ý molecular dyes have the potential to deliver many D(UV) dye-antibody conjugates for the spectral flow cytometry market with differentiated colours to allow multiplexing beyond the ~50 limit seen to date with the recent emergence – and rapid market uptake – of commercial spectral flow cytometers, e.g. Thermofisher Scientific (Bigfoot), Sony Biotechnology [...]
