Greater selection of NucSpot® Nuclear Stains promotes further precision, efficiency, and reliability in cell imaging with selective nuclear targeting and exceptional photostability.
Fremont, CA, February 21, 2024 – Life Science Newswire – Biotium, a leader in fluorescent dyes for life science research, announces the expansion of its NucSpot® Nuclear Stains lineup, offering unprecedented specificity and flexibility for nuclear counterstaining. NucSpot® Nuclear Stains are membrane-impermeant, targeting the nucleus selectively with minimal fluorescence until binding to DNA, enabling convenient no-wash nuclear staining. Unlike traditional options such as propidium iodide (PI), TO-PRO®, or TOTO®, NucSpot® achieves nuclear specificity in fixed and permeabilized cells without the need for RNase treatment.
Now with an extensive selection of 9 colors spanning the fluorescence spectrum from green to near-infrared (near-IR), NucSpot® Nuclear Stains provide greater panel flexibility, compatible with FITC, Cy®3, PE, Texas Red®, Cy®5, APC, Cy®5.5, and Cy®7 channels. Several options are non-toxic, suitable for cell cycle profiling by flow cytometry, and can be incubated in live cultures for multi-day imaging.
"These new additions to our cellular stains line provide a major improvement by broadly expanding scientists’ color choice for nuclear counterstaining. Plus, NucSpot® Nuclear Stains are much more photostable than existing cyanine-based nuclear stains, and there’s no need to treat with RNase for nuclear staining." says Dr. Lori Roberts, Director of Bioscience at Biotium. "These novel dyes are products of our commitment to providing cutting-edge and convenient tools for cell biology research."
