    Paper-Based Biosensors: Effective and Efficient
    Paper-Based Biosensors: Effective and Efficient There has been a recent shift in research science and medical communities towards the use of efficient, cost effective biosensors that can test for food and water contamination, monitor biological processes in humans, determine accurate medical diagnoses, and more. Paper-based biosensors are of particular interest. Researchers and medical professionals alike need safe and less costly...
  2. Advances in Lab-on-a-Chip Technology: Ionophores & Enzymes in Biosensors

    Advances in Lab-on-a-Chip Technology: Ionophores & Enzymes in Biosensors
    Advances in Lab-on-a-Chip Technology Lab-on-a-chip (LOC) technology is a category of research microdevices that automate several lab techniques in one chip; in this case a chip typically measured at a few square centimeters. In addition, currently on trend are nanomaterials such as carbon nanotubes (a popular choice due to the chemical stability and strength of the material), used in the...
  3. Ion Exchange Membranes for Electrodialysis

    Ion Exchange Membranes for Electrodialysis
    Ion Exchange Membranes for Electrodialysis Ion exchange membranes (IEMs) are semi-permeable membranes that are used to control the type of dissolved ions or neutral molecules transported through an object. IEMs are manufactured from diverse materials, which serve a wide range of functions across different industries. More IEM applications are being innovated with the discovery of new suitable materials, which differ...

    Beta-Lactamase and Microbial Antibiotic Resistance
    β-Lactamases continue to be the leading cause of resistance to β-lactam antibiotics among gram-negative bacteria. In recent years there has been an increased incidence and prevalence of extended-spectrum β-lactamases (ESBLs), enzymes that hydrolyze and cause resistance to oxyimino-cephalosporins and aztreonam.
  6. RNase A: Frequently Asked Questions

    RNase A: Frequently Asked Questions
    Introduction to RNase Ribonucleases (RNases) are a large group of hydrolytic enzymes that degrade ribonucleic acid (RNA) molecules. These are nucleases that catalyze the breakdown of RNA into smaller components. They are a superfamily of enzymes which catalyze the degradation of RNA, operating at the levels of transcription and translation. 3D conformation of ribonuclease A enzyme These enzymes are present...
  7. IPTG Triggers the Transcription of the Lac Operon

    IPTG Triggers the Transcription of the Lac Operon
    Isopropyl β-D-1-thiogalactopyranoside, abbreviated IPTG, is a molecular biology reagent. This compound is used as a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon.
  8. Frequently Asked Questions About Proteinase K

    Frequently Asked Questions About Proteinase K
    In molecular biology Proteinase K (also protease K or endopeptidase K) is a broad-spectrum serine protease. The enzyme was discovered in 1974 in extracts of the fungus Engyodontium album (formerly Tritirachium album). Proteinase K is able to digest native keratin (hair), hence, the name "Proteinase K". The predominant site of cleavage is the peptide bond adjacent to the carboxyl group of aliphatic and aromatic amino acids with blocked alpha amino groups. It is commonly used for its broad specificity.
  9. 20 FACTS ABOUT PROTEASOMES & PROTEASOME INHIBITORS!

    1. Proteasome inhibitors are drugs that block the action of proteasomes, cellular complexes that break down proteins, like the p53 protein. Proteasome inhibitors are being studied in the treatment of cancer, especially multiple myeloma.
  10. Chymostatin (Protease Inhibitor) - Frequently Asked Questions

    Microbial product, chymostatin was discovered by H. Umezawaet al.v in 1970 by testing the anti-chymotrypsin activity of culture filtrates. Since the amino acid analysis of different samples gave variable ratios of phenylalanine, leucine, valine and isoleucine, chymostatin was considered to be a mixture of similar peptides with minor differences. Attempts to separate the components were unsuccessful.
