摘要:
The present invention relates to methods of detecting, in a sample, embryonic stem cells, induced pluripotent stem cells, and/or cells undergoing reprogramming to produce induced pluripotent stem cells. These methods include providing a sample potentially containing such cells and providing a rosamine derivative compound of the formula (I): where the rosamine derivative compound selectively produces fluorescent signals for embryonic stem cells, induced pluripotent stem cells, and/or cells undergoing reprogramming to produce induced pluripotent stem cells. These methods also include the steps of contacting the sample with the rosamine derivative compound and detecting the presence of the embryonic stem cells, induced pluripotent stem cells, and/or cells undergoing reprogramming to produce induced pluripotent stem cells based on fluorescent signals emitted by the sample following said contacting.
摘要:
A compound for detecting an analyte using Surface Enhanced Raman Spectroscopy (SERS) and a method of forming the compound is provided. The compound has Formula I: wherein W is selected from the group consisting of an optionally substituted aryl group and an optionally substituted heteroaryl group; each Y independently is NR1R2, wherein R1 and R2 are independently selected from the group consisting of H and C1-C6 alkyl, or R1 and R2 combine to form together with the nitrogen to which they are attached a heterocyclic group with 4 to 5 carbon atoms, is used to denote a single or a double bond, and Z is NH, NH2, NH—(C═O)—(CH2)n—SH, wherein n=1 to 10, or or a tautomer or stereoisomer thereof, or a salt thereof. A method and device for detecting an analyte using Surface Enhanced Raman Spectroscopy (SERS) is also provided.
摘要:
Triazine linkers can be used to prepare universal small molecule chips for functional proteomics and sensors. These triazine linker compounds are prepared by making a first building block by adding a first amine by reductive amination of triazine, making a second building block by adding a second amine to cyanuric chloride, and combining the first and second building blocks by aminating the first building block onto one of the chloride positions of the second building block. These triazine linkers are then linked to a substrate for determining binding affinity of proteins.
摘要:
Charged and neutral small fluorescent molecules based upon the styryl scaffold are useful as imaging agents for misfolded proteins such as amyloid plaque. Charged molecules are prepared using pyrrolidine catalyzed reactions by solution-phase synthesis. Neutral styryl molecules are prepared using acetic anhydride catalyzed reactions, Horner-Emmons reactions or Wittig reactions.
