Abstract:
The invention relates to novel substrates and methods for staining live stem cells. The stain may be used to identify induced pluripotent stem cell colonies during the process of somatic cell reprogramming.
Abstract:
Los compuestos de rodamina sustituidos con silicio se describen en la presente. En la presente se describen también tintes de SiR que comprenden al menos un grupo vinilo unido al átomo de Si (posición 10) del tinte de SiR. También se proporcionan derivados, versiones funcionalizadas, conjugados, kits, métodos sintéticos relacionados y usos de compuestos de SiR. Los tintes de silicio-rodamina (SiR) pueden proporcionar una fluorescencia brillante en longitudes de onda de rojo lejano y mostrar buena fotoestabilidad. Los compuestos descritos en la presente pueden ser útiles para el marcado fluorescente y la detección de muestras biológicas.

Abstract:
The present disclosure is directed dye compounds containing a hydrazinyl substituent and optionally, one or more negatively charged groups, such as sulfonate, phosphate, phosphonate, and/or carboxylate groups and dye compounds containing an aminooxy substitutent. The compounds are useful in the detection of analytes containing aldehyde and ketone groups, including, for example, glycans.
Abstract:
Disclosed are benzoxazole-based compounds, kits, and methods of producing and using the described compounds in fluorescence-based detection of analytes (e.g., metal ions). Also disclosed are uses of benzoxazole-based compounds as ratiometric metal ion indicators.
Abstract:
Provided herein are methods, compositions and kits for use in the site-specific labeling of glycoproteins comprising a combination of enzyme-mediated incorporation of modified sugars comprising a chemical handle and cycloaddition chemistry with a labeling molecule comprising a reactive group, a metal ion chelator, and/or a fluorophore.
