Method, system and computer software for variant information via a web portal
Abstract of Disclosure A genomic web portal is described that receives from a user over the Internet a selection of identifiers of probes for detecting biological molecules. The portal may also receive hybridization intensity values produced from biological probe array experiments. The portal determines alternative splice variants based on factors that may include the hybridization intensity values. The portal correlates alternative splice variants with annotation data and provides for the user a graphical representation of the alternative splice variants and the correlated annotation data. The selection of annotation data to be displayed may be based on a user selection of a genomic, primary-transcript, mRNA, or protein display type. The annotation data may include genomic sequence; presence or relative abundance of alternative splice variants; exon arrangement, content, or sequence; frequency of exon usage in alternative splice variants; RNA, gene, or protein identification, function, structure, or sequence; probe arrangement; and other data.

The invention provides methods, reagents and kits for amino acid, peptide and protein identification, differential quantitation and for the analysis of post translational modification and cross-linking status, comprising: derivatizing a mixture of amino acids peptides or proteins, to form at least one amino acid peptide or protein containing a fixed-charge ion, other than at the C-terminal or N-terminal end thereof; introducing the mixture of amino acids peptides or proteins containing the fixed charge derivatized amino acid peptide or protein to a mass spectrometer; passing the mixture of amino acids peptides or proteins containing the fixed charge derivatized amino acid peptide or protein through a first mass resolving spectrometer to select precursor protein or peptide ions having a first desired mass-to-charge ratio; subjecting the precursor ions of the first mass to charge ratio to dissociation to form a product ion having a second mass-to-charge ratio that is characteristic of a fragmentation occurring at a site adjacent to the fixed charge; and detecting the product ions having the second mass-to-charge ratio. The product ion having the second mass-to-charge ratio may be either a product ion formed by neutral loss of the fixed charge from the precursor ion, or a product ion formed by charged loss of the fixed charge from the precursor ion.

Protein identification from protein product ion spectra
InactiveUS20050221500A1Expand databaseAccurately reflectParticle separator tubesSamplingMass Spectrometry-Mass SpectrometryNatural abundance
Mass spectrometry is used to identify a protein of interest. The protein is first ionized then fragmented into protein product ion. Masses of the observed product ions are compared to product ion masses calculated in silico for database protein sequences to identify product ion matches within a predetermined mass tolerance. An algorithm that weights the product ion to matches based upon one or more factors such as product ion abundance, favored cleavage sites, product ion type, precursor ion charge state and polarity is used to score the possible matches to database proteins in order to identify the protein of interest. The invention represents a “top down” approach and is particularly well-suited for identification of a protein in a complex mixture.

Isotope-coded ionization-enhancing reagents (ICIER) for high-throughput protein identification and quantitation using matrix-assisted laser desorption ionization mass spectrometry
InactiveUS6905879B2Quantitative precisionReduce disulfide bondSamplingComponent separationLaser desorption ionization mass spectrometryArginine
Arginine-containing cysteine-modifying compounds useful for MALDI-MS analysis of proteins are provided. These compounds termed isotope-coded ionization enhancement reagents (ICIER) can provide ionization enhancement in MALDI-MS, relative quantitation, and additional database searching constraints at the same time without any extra sample manipulation. More specifically, ICIER increase the ionization efficiency of cysteine-containing peptides by attachment of a guanidino functional group. ICIER also increase the overall hydrophilicity of these peptides due to the hydrophilic nature of ICIER and thus increase the percentage of recovery of these peptides during sample handling and processing such as in-gel digestion or liquid chromatography. Finally, a combination of both light and heavy ICIER provides an accurate way to obtain relative quantitation of proteins by MALDI-MS and additional database searching constraints (number of cysteine residues in every single peptide peak) to increase the confidence of protein identification by peptide mass mapping.

Method for creating multiply charged ions for MALDI mass spectrometry (ESMALDI)
A method of combining ES (ElectroSpray Ionization) and MALDI (Matrix Assisted Laser Desorption Ionization) to create enhanced MALDI mass spectrometry to be referred to as ESMALDI (ElectroSpray Matrix Assisted Laser Desorption Ionization). ESMALDI technology offers substantial advantages over conventional technology. essentially by combining the high ionization efficiency and multiple charging of ions in ESI with the smaller sample requirements and operational simplicity of MALDI. Biologists should thus be able to achieve higher sensitivity, better protein identification, enhanced quantification potential and enhanced structural information. An additional degree of freedom for ESMALDI MS is flexibility in the choice of solvents that can be used in the ESI component of the process. Substantial differences in ESI behavior can occur with the same analyte or mixture of analytes in different solvents. Such differences often provide clues to the properties of the analyte and its ions which cannot be readily obtained from conventional MALDI experiments.
