  • A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. (thermofisher.com)
  • It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. (thermofisher.com)
  • NK cells are specialized effectors of the innate immune system that destroy their targets by antibody-dependent cell-mediated cytotoxicity, have prominent antitumor effects, and are potent killers of virally infected cells. (medscape.com)

  • A statistical analysis of intravital microscopic images recorded from the knee joints of untreated control mice during an early time span of 24 hours after the transfer of anti-CII mAbs [ 10 ] revealed an antibody-induced increase in leukocyte adhesion to the vessel walls. (biomedcentral.com)
  • Plasma from peripheral blood was collected to measure tumor necrosis factor-a (TNF-α) and interleukin-8 (IL-8) by ELISA and nitrite (NO3) using a Griess assay. (bvsalud.org)
  • This promotes the firm adhesion of the leukocytes through integrin-mediated binding, such as VLA-4 that binds to VCAM- 1, or LFA-1 to ICAM-1. (wearecellix.com)
  • Once migrated into the SAS, T cells show an active motility behavior, which is a prerequisite for cell-cell communication, in situ reactivation and neuroinflammation. (bvsalud.org)
  • The fact that the RBD region of Rhotekin has a high affinity for GTP-RhoA and that Rhotekin binding results in a significantly reduced intrinsic and catalytic rate of GTP hydrolysis make it an ideal tool for affinity purification of GTP-RhoA from cell lysates. (cytoskeleton.com)
  • Specifically, methods are disclosed for mobilizing hematopoietic stem cells into a subject's peripheral blood. (justia.com)
  • Therefore, hematopoietic stem cells mobilized into a subject's peripheral blood by the method of the invention is useful as a source of donor cells in bone marrow transplantation for the treatment of a variety of disorders, including cancer, anemia, autoimmunity and immunodeficiency. (justia.com)
  • The various mature blood cell types are all ultimately derived from a single class of progenitor cell known as hematopoietic stem cells. (justia.com)
  • Other cell types derived from hematopoietic stem cells include platelets and erythrocytes. (justia.com)
  • The use of high-dosage chemotherapy or radiotherapy for bone marrow ablation requires subsequent incorporation of hematopoietic stem cells into the patient, in which case prior harvesting of such cells is required. (justia.com)
  • In many cases, successfully mobilization is not effected in the patient and inadequate numbers of hematopoietic stem cells are harvested from these patients using current methods. (justia.com)
  • These increases in local Na + levels boost proinflammatory and antimicrobial macrophage activity and can favor polarization of T cells towards a proinflammatory Th17 phenotype. (frontiersin.org)
