  • cytoplasm
  • Cytoplasm - contents of the main fluid-filled space inside cells, chemical reactions also happen in this jelly-like substance. (wikipedia.org)
  • Organelle - term used for major subcellular structures Peroxisomes - a very small organelle that uses oxygen to breakdown and detoxify long fatty acids and other molecules Pili - also called fimbria is used for conjugation and sometimes movement Ribosome - RNA and protein complex required for protein synthesis in cells Starch grain - found in the cytoplasm of a typical plant cell, it stores chemical energy of the plant.

  • zonal
  • He worked at the Oak Ridge National Laboratory for 21 years, where he invented the zonal ultracentrifuge for subcellular fractionation and organized a joint National Institutes of Health and Atomic Energy Commission program to develop methods for the isolation of oncogenic viruses. (aacc.org)
  • blood
  • A method for separating plasma from red blood cells and a device utilizing the method in which a low-pressure filter is interposed in a pathway between an inlet port and a reaction area. (google.com.au)
  • For example, red blood cells (erythrocytes) scatter and absorb light and could adversely affect a measurement of either reflected or transmitted light of a diagnostic test relying on either of these measurement techniques. (google.com.au)
  • The techniques generally utilize a filtering device capable of separating red blood cells from plasma. (google.com.au)
  • It is an extracorporeal blood separation method whereby whole blood is extracted from a donor or patient, the red blood cells are separated, and the remaining blood is returned to circulation. (wikipedia.org)
  • For the separation of erythrocytes, whole blood is passed through an apparatus that isolates the red blood cells from the remaining components. (wikipedia.org)
  • This is because the hematocrit, or the percentage of blood volume taken up by red blood cells, is present in the highest percentage of all blood cell components in the solid portion of blood. (wikipedia.org)
  • The centrifugal force will separate the red blood cells from other cells due to their high specific weight. (wikipedia.org)
  • citation needed] Therapeutic erythrocytapheresis is commonly used to remove red blood cells in patients experiencing sickle cell crisis. (wikipedia.org)
  • This blood separation is also used in patients with severe malaria. (wikipedia.org)
  • After removal of the affected cells, the patient can then be transfused with a dose of normal red blood cells. (wikipedia.org)
  • This includes either two standard units of red blood cells or one unit plus of red blood cells and another of either plasma or platelets. (wikipedia.org)
  • The advantage to the blood bankers is the on-line separation into standardized RBC masses with the subsequent reduction in testing, data entry and staffing. (wikipedia.org)

  • Biomanufacturing products are recovered from natural sources, such as blood, or from cultures of microbes, animal cells, or plant cells grown in specialized equipment. (wikipedia.org)
  • Because of the versatility of the technique, a wide range of protocols for the separation of samples like rare metal ions, protein isoforms, multiprotein complexes, peptides, organelles, cells, DNA origami, blood serum and nanoparticles exist. (wikipedia.org)
  • Blood fractionation is the process of fractionating whole blood, or separating it into its component parts. (wikipedia.org)
  • In whole blood, red blood cells, leukocytes, and platelets are suspended within the plasma. (wikipedia.org)
  • The first practical large-scale method of blood plasma fractionation was developed by Edwin J. Cohn during World War II. (wikipedia.org)
  • multicellular organisms
  • Cell biology research extends to both the great diversity of single-celled organisms like bacteria and the many specialized cells in multicellular organisms like humans. (bionity.com)
  • Multicellular - Organisms consisting of more than one cell and having differentiated cells that perform specialized functions. (wikipedia.org)
  • Cellular differentiation - A concept in developmental biology whereby less specialized cells become a more specialized cell type in multicellular organisms. (wikipedia.org)
  • Nuclear
  • DNA-binding reactions were performed using 20 fmol biotin-labeled DNA duplex (1 Êbiotin per strand) and 2 µL (6.8 µg total protein) NE-PER nuclear extract prepared from HeLa cells. (thermofisher.com)
  • biology
  • Advances in modern cell biology and physiological techniques have dramatically improved our understanding of basic cellular functions. (nih.gov)
  • Molecular Biology of the Cell. (wikipedia.org)
  • Cell biology (also called cellular biology or formerly cytology , from the Greek kytos , "container") is an academic discipline that studies cells . (bionity.com)
  • Research in cell biology is closely related to genetics , biochemistry , molecular biology and developmental biology . (bionity.com)
  • Cell biology can be described as all of the following: Branch of science - A systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. (wikipedia.org)
  • Cell biology - (formerly cytology) The study of cells. (wikipedia.org)
  • Cell biology or cytology or cytobiology, (from the Greek κυτος, kytos, "vessel") is a branch of biology that studies the different structures and functions of the cell and focuses mainly on the idea of the cell as the basic unit of life. (wikipedia.org)
  • Cell biology focuses more on the study of eukaryotic cells, and their signalling pathways, rather than on prokaryotes which is covered under microbiology. (wikipedia.org)
  • extraction
  • The use of selective detergent extraction eliminates the hassle of phase separation based on hydrophobicity, allowing better reproducibility and higher throughput. (thermofisher.com)
  • Classical qualitative methods use separations such as precipitation, extraction, and distillation. (wikipedia.org)
  • Cytoskeleton
  • Virtually all cytolytic responses require actin cytoskeleton rearrangements for proper cell adhesion, immune synapse formation, sustained signaling, and delivery of lytic granules to the target cell ( 9 - 11 ). (pnas.org)
  • disruption
  • Disruption of WIP expression by RNAi surprisingly did not affect cell adhesion and conjugation, but severely impaired lytic granule polarization to the immune synapse, resulting in inhibition of NK cell cytotoxic activity. (pnas.org)
