    摘要: Specific peptides, and derived ionization characteristics of the peptides, from the Insulin Receptor protein (IR), and its isoforms IR-A and IR-B, that are particularly advantageous for quantifying the IR protein, IR-A isoform and/or IR-B isoform, directly in biological samples that have been fixed in formalin by the method of Selected Reaction Monitoring (SRM) mass spectrometry, or what can also be termed as Multiple Reaction Monitoring (MRM) mass spectrometry. Such biological samples are chemically preserved and fixed and are 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 said biological sample using the Liquid Tissue™ reagents and protocol and the IR protein, and IR-A and/or IR-B isoforms, 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 an IR peptide is phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.

    摘要: Specific peptides, and derived ionization characteristics of those peptides from Death Receptor 5 (DR5) protein are provided that are particularly advantageous for quantifying the DR5 protein directly in biological samples that have been fixed in formalin by the method of Selected Reaction Monitoring/Multiple Reaction Monitoring (SRM/MRM) mass spectrometry. Such biological samples are chemically preserved and fixed wherein 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 a biological sample using the Liquid Tissue™ reagents and protocol, and the DR5 protein are 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 for one or more of the DR5 protein. These peptides can be quantitated if they reside in a modified or in an unmodified form. An example of a modified form of a DR5 peptide is phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.

    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.

    摘要: The current disclosure provides for specific peptides, and derived ionization characteristics of the peptides, from the Receptor Tyrosine-Protein Kinase erbB-3, or Her3, that are particularly advantageous for quantifying the Her3 protein directly in biological samples that have been fixed in formalin by the method of Selected Reaction Monitoring (SRM) mass spectrometry, or what can also be termed as Multiple Reaction Monitoring (MRM) mass spectrometry. Such biological samples are chemically preserved and fixed wherein said 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 said biological sample using the Liquid Tissue™ reagents and protocol and the Her3 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 Her3 peptide is phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.
