摘要:
The present disclosure provides methods, device, assemblies, and systems for dispensing and visualizing single cells. For example, provided herein are systems and methods for dispensing a dispense volume into a plurality of wells of a multi-well device, where, on average, a pre-determined number of cells (e.g., 1-20) are present in the dispense volume, and determining, via a cellular label, the number of cells present in each of the plurality of wells. Such dispensing and cell detection may be repeated a number of times with respect to wells identified as having less than the pre-determined number of cells in order increase the number wells in the multi-well device containing the desired number (e.g., a single cell).
摘要:
Specific peptides are provided, and derived ionization characteristics of those peptides, from the Hepatocyte Growth Factor Receptor (cMET) protein. The peptides are particularly and surprisingly advantageous for quantifying by the method of Selected Reaction Monitoring (SRM) mass spectrometry the cMET protein directly in biological samples that have been fixed in formalin, or what can also be termed as Multiple Reaction Monitoring (MRM) mass spectrometry. Such biological samples are chemically preserved and fixed where the biological sample is selected from tissues and cells treated with formaldehyde containing agents/fixatives including: formalin-fixed tissue/cells; formalin-fixed/paraffin embedded (FFPE) tissue/cells; FFPE tissue blocks and cells from those blocks; and tissue culture cells that have been formalin fixed and or paraffin embedded. A protein sample is prepared from the biological sample using the Liquid Tissue™ reagents and protocol and the cMET protein is quantitated in the Liquid Tissue™ sample by the method of SRM/MRM mass spectrometry by quantitating in the protein sample at least one or more of the peptides described. These peptides can be quantitated if they reside in a modified or an unmodified form. An example of a modified form of a cMET peptide is phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.
