  • The Thermo Scientific 1-Step Human High-Yield In Vitro Translation (IVT) Kits enable the expression of functional proteins with 10 to 100 times greater yield per mL than other mammalian IVT systems. (thermofisher.com)
  • Following this translation event, proteins often need additional modifications by enzymes. (news-medical.net)
  • Proteomics is the study of all the proteins that an organism makes, how they are modified by other enzymes, and the roles they play in a living organism. (news-medical.net)
  • Allergen avoidance strategies including personal protective equipment, engineering controls, protein encapsulation, and reduction of airborne enzyme concentrations are required to mitigate occupational exposure to fungal enzymes. (cdc.gov)
  • Entry into the host cell is achieved by attachment of the viral G glycoproteins to host receptors, which mediates clathrin-mediated endocytosis. (wikipedia.org)
  • This process depends on the general physico-chemical features of the cargo membrane protein and on the interactions of these features with the collective properties of the bilayer, instead of the one-to-one intermolecular interactions that exist between discrete signals and their receptors. (biologists.com)
  • At least 2 cellular receptors for EV have been identified: a subunit of the integrin molecule VLA-2 that binds types 1 and 8, and a complement regulatory protein (ie, a decay accelerating factor) that binds types 6, 7, 12, and 21. (medscape.com)
  • A study by Chow et al (2008) reported that human bocavirus was detected by PCR in respiratory specimens from 4 of 273 (1.5%) hospitalized adults in whom no alternate viral etiology was identified. (medscape.com)
  • Alanine aminotransferase measurements are used in the diagnosis and treatment of certain liver diseases (e.g., viral hepatitis and cirrhosis) and heart diseases. (cdc.gov)
  • Albumin measurements are used in the diagnosis and treatment of diseases involving the liver and/or kidneys, and are frequently used to assess nutritional status because plasma levels of albumin are dependent on protein intake. (cdc.gov)
  • The coat on the budding vesicle comprises two layers, an inner layer of adaptor proteins (gray ovals) and an outer layer that forms a polyhedral cage. (biologists.com)
  • Furthermore, truncation of the HN cytoplasmic tail was found to be inhibitory toward budding, since it prevented coexpressed wild-type (wt) F protein from directing VLP budding. (nih.gov)
  • Conversely, truncation of the F protein cytoplasmic tail was not inhibitory and did not affect the ability of coexpressed wt HN protein to direct the budding of particles. (nih.gov)
  • Coexpression of M protein with the viral hemagglutinin-neuraminidase (HN) or fusion (F) glycoproteins also failed to result in significant VLP release. (nih.gov)
  • Similarly, instead of retroviruses, one can think of bacteria or fungi, which do not possess 'gag pol Protein. (thesaurus.net)
  • Administration of ribavirin is accomplished using a small-particle aerosol generator. (rtmagazine.com)
  • Researchers said that using gum to reduce viral loads in saliva could add to the benefit of vaccines and would be particularly useful in countries where vaccines are not yet available or affordable. (mirror.co.uk)
  • and positive regulation of peptidyl-serine phosphorylation of STAT protein. (nih.gov)
  • The symptoms of viral and bacterial illnesses are sometimes similar. (medicinenet.com)
  • Surface proteins of Staphylococcus aureus play vital roles in bacterial physiology and pathogenesis. (bvsalud.org)
  • Then it destroys the cell, busting it open to release its newly formed viral particles. (upworthy.com)
  • Nonstructural protein 1 (NS1) is a DNA-binding protein involved in gene transcription. (medscape.com)
  • A tRNA(3)-Lys binds to the primer-binding site (PBS) situated at the 5'-end of the viral RNA. (proteopedia.org)
  • The authors propose that Aβ is among the proteins that enhance HSV1 infectivity. (alzforum.org)
  • The finding that HSV1 accumulates a protein corona is potentially an important advance in understanding viral infectivity. (alzforum.org)
  • The viral core protein retains protease activity, needed for cleavage from a protein precursor. (virology.ws)
  • Conversion of viral genomic RNA into dsDNA requires many steps. (proteopedia.org)
