Antibody Staining Protocol Fc Block of Cells from Tissues 1. Phagocytic cells (such as macrophages and granulocytes) can bind non-specifically to antibodies unless the Fc receptors of these cells are blocked. If the sample is from a tissue homogenization possibly containing macrophages, or from a ...
if cells are to be collected for functional assays. It inhibits metabolic activity. Flow cytometry intracellular staining protocol General procedure describing detection of intracellular proteins in flow cytometry Fixing and permeabilization: For intracellular staining, cells can be fixed first to ensure ...
to your stain will incidentally also saturate most other potential unspecific bindings, as they were outlined under. Therefore, adding unconjugated antibody to your surface and also your intracellular staining cocktails will reduce unspecific binding. ...
protocol could not be applied to separate other cell types of forensic significance. Di Nunno et al. [16] introduced a modified protocol for use of FACS in a case study, although no further case reports are presented in the literature. No studies have been ...

on the cell surface can be investigated; Extended Data Fig.8b). We did not observe an antigen-specific plasmablast population (RBD+) in the sample without capture reagent, providing evidence that the antibodies we discovered could not have been identified by FACS surface staining alone under ...
for potential contaminant. The plates were then placed in a thermocycler for 30 min at 37 °C and 30 min at 75 °C. The iTag PCR was performed directly on the cell lysate following the JGI standard operating protocol (https://jgi.doe.gov/user-program-info/pmo-overview/protocols...
Titration experiments are easy to perform, and there are several papers that discuss this process1,2. This protocol has been optimized for 1×106cells in 50 µl final volume. All staining is performed on ice, in the dark, for 20 minutes. Identify the 1x concentration, which is the manu...
