I always look forward to sharing the Nucleic Acids Research (NAR) database issue . This year's blog topic is immunology. The NAR archive lists 31 immunologic databases, but only seven or so are active, and others are not listed in the NAR archive. Read the blog learn more.
DNA sequencing-based immunoprofiling quantitatively measures AR diversity in samples by determining the sequences of V(D)J junctions. AR receptor diversity is vast due to a combinatorial rearrangement process that inserts a variable number of random DNA bases at each junction. In the sequencing process V(D)J junctions are amplified with V and J gene specific primers and, to be quantitative, differences in amplification rates that are due to primer sequences must be factored into each assay.
Immunoprofiling is the quantitative measurement of antigen receptors (ARs; antibodies or T-cell receptors) in a sample and is a hot area in biotechnology. Immunoprofiling is used to assess the diversity of antigen receptors (ARs: antibodies and T-Cell receptors) and how this diversity changes in response to allergens, infections, or vaccines. In cancer therapy, Immunoprofiling is used to develop biomarkers and understand how an individual’s immune cells fight tumors, and predict individuals' response to immunotherapy.
Last week I attended my first NSF ATE PI meeting. As a contributing member of Digital World Biology's ATE project entitled " A Bridge to Bio-Link's Future ," I participated in the conference by preparing and staffing our booth in the first evening's showcase.
As a brief background, the NSF (National Science Foundation) ATE (Advanced Technology Eduction) program celebrated its 25 th anniversary this year. ATE's mission is to support innovations in technical ... Read more
A fun thing we can do with molecular models is to create art. In Molecule World™ , the residue coloring option applies a different color to each amino acid and nucleotide. When we're characterizing a protein and trying to understand its function, the residue coloring option helps us identify repetitive or unusual amino acid sequences, but we can also use this coloring option to have fun.
The video at the end shows all the steps put together.

Cytochrome C oxidase is a molecule that none of us air-breathing creatures can live without. It's also really interesting. This protein complex is a dimer of two smaller complexes. Each of the smaller complexes contains 13 different proteins and two heme groups.
Oxidized Cytochrome C Oxidase. Each protein chain is colored differently. Arrows point to the active site in subunit I.
The two heme groups are both part of the cytochrome c oxidase subunit I protein. The DNA sequence of this protein is used for many types of DNA barcoding.
We created the structure collection feature in Molecule World because I knew it would be useful in teaching my courses. A request from the Weisman Art Museum at the University of Minnesota taught us structure collections could be useful in other ways, too.
The Weisman Art Museum collaborated with neuroscientists at the University of Minnesota and Ricardo Martinez Murillo, a neuroscientist in Spain, to produce the traveling Beautiful Brain exhibit featuring the drawings of Santiago Ramón y Cajal. Cajal is considered the father ... Read more
BCRs (antibodies) and TCRs (T cell receptors) are the recognition molecules of our immune system; the molecules they bind are called antigens. BCRs and TCRs are similar in many ways, but their differences form the core of how self and non-self are recognized.
Immuno-bioinformatics is a fast growing subdiscipline of immuno-biotechnology. New technologies like immune-profiling and targeted cancer therapies are leading to job growth and demands for new skills and knowledge in biomanufacturing, quality systems, informatics, and cancer biology.
