Abstract: Described herein are methods, compositions, kits and systems for multiplexed detection of target molecules from a sample. In some embodiments, the methods, compositions, kits and systems can be used to perform multiplexed protein analysis of a sample (e.g., a sample comprising a small number of cells or a single-cell sample). In some embodiments, the same sample subjected to a multiplexed protein analysis using the methods, compositions, kits and systems described herein can also be subjected to a nucleic acid (e.g., RNAs, microRNAs, and/or DNA) analysis, thereby creating an integrated expression profiling from a limited amount of sample.

Abstract: Provided herein are compositions containing photoactivatable caged tamoxifen and tamoxifen derivative molecules. Also provided are kits containing one of these compositions and a light source. Also provided are methods of optically inducing nuclear translocation of a fusion protein containing a mammalian estrogen receptor ligand binding domain in a eukaryotic cell and methods of optically inducing recombination in a eukaryotic cell that include contacting a eukaryotic cell with at least one of these compositions. Also provided are methods of treating breast cancer in a subject that include administering a photoactivatable caged tamoxifen or tamoxifen derivative molecule to a subject having breast cancer.
