  • In-vivo, mAb biotherapeutics can exist in multiple forms i.e. free (bivalently unbound), partially free (monovalently bound) and the fully bound drug (bivalently bound). (betasciencepress-publishing.com)
  • However, only after 10 immunizations over a period of about 6 months could we detect antibodies that competed efficiently with the binding of IgE to rat basophilic leukemia (RBL) cells. (huji.ac.il)
  • B cells have antibody-dependent and antibody-independent pathogenic functions. (hindawi.com)
  • Independent of antibody secretion B cells secrete proinflammatory cytokines, support the formation of ectopic GCs, and serve as antigen presenting cells. (hindawi.com)
  • Left panel: antigen bound by antibody is taken up via FcR on APCs such as dendritic cells or macrophages. (hindawi.com)
  • In this grant, we are investigating a new immunization concept that is based on the utilization of anti-idiotypic antibodies against the germline form of targeted BCRs as tools to specifically expand naïve B cells that express such BCRs, focusing on VRC01-class BCRs. (washington.edu)
  • Transmembrane or otherwise tumor-associated polypeptides specifically expressed on the surface of cancer cells as compared to normal, non-cancerous cell(s) have been identified as cellular targets for cancer diagnosis and therapy with antibodies. (justia.com)
  • Characterization of angiotensin II (AT2) binding sites in R3T3 cells. (aspetjournals.org)
  • 4 X l0⁵ sites/cell) binding site, Hill analysis of the saturation binding data strongly suggested that EMC-D virus has more than one binding site on BMP cells. (mun.ca)
  • It is concluded that the receptor for EMC-D virus on BMP cells is a sialylated glycoprotein, and virus binding involves Neu5Ac, and possibly Neu5Gc, but not N-linked sugars. (mun.ca)
  • Monoclonal antibodies raised against the putative receptor blocked EMC-D virus infection of BMP cells and virus binding to β-cells from SJL/J mice. (mun.ca)
  • The method entails optionally subjecting a sample to conditions suitable for expansion of one or more of the lymphocytes to form an expanded sample comprising antibody secreting cells (ASCs) and distributing the sample into containers to provide a plurality of subsamples. (justia.com)
  • T cells are involved in cell-mediated immunity whereas B cells are primarily responsible for humoral immunity (relating to antibodies). (wellnessadvantage.com)
  • B cells respond to pathogens by producing large quantities of antibodies which then neutralize foreign objects like bacteria and viruses. (wellnessadvantage.com)
  • MAb K20, likewise mAb K10, proved to be fungicidal in vitro against KT-sensitive Candida albicans cells, an activity neutralized by mAb KT4, and was capable of binding to b-1,3- glucan. (unime.it)
  • Due to the similarity between anti-ID Abs and anti-drug antibodies, anti-ID Abs are also commonly used as a reference standard for antibody drug immunogenicity, anti-drug antibody (ADA) studies and neutralization antibody measurement. (genscriptprobio.com)
  • We raised anti‐anti‐IgE antibodies in an attempt to obtain anti‐Id capable of interacting with the Fcϵ receptor (FcϵR). (huji.ac.il)
  • One of the first critical steps in an effective antibody response is the recognition of a foreign antigen by a membrane anchored B cell receptor (BCR) on the surface of a naïve B cell. (washington.edu)
  • Tienen un empleo potencial en el tratamiento del SIDA ya que poseen propiedades de unión a gp120 y de bloqueo del VIH de rCD4 así como una gran semivida plasmática y funcioones de unión al receptor Fc de la inmunoglobulina. (bvsalud.org)
  • The actin cytoskeleton and associated actin-binding proteins form a complex network involved in a number of fundamental cellular processes including intracellular trafficking. (edu.au)
  • In plants, both actin and myosin have been localised to plasmodesmata, and thus it is likely that other actin-binding proteins are also associated with plasmodesmata structure or function. (edu.au)
