Fernandez said, despite being trapped and baked within a polymer, cell staining shows that the cultured cells remained alive.
Before then, he would have relied primarily on fixed cell staining, which amounted to taking a handful of snapshots portraying a complex chemical interaction while whatever might be happening in between each picture remained unknown.
The staining intensity was evaluated according to the immunoreactivity-staining score, first introduced by Remmele et al [25] based on the semiquantitative scoring of cell staining as follows: grade (-), no staining; grade 1 (+), mild but definite staining; grade 2 (++), moderate staining; grade 3 (+++), strong staining.
Brilliant Violet 421[TM] antibodies are fully compatible with currently used buffers and fixatives, and common cell staining techniques, suitable for both surface and intracellular staining of antigens.
Ultimately, the interface pattern was not considered for PD-L1 companion diagnostic development using the 22C3 antibody for NSCLC because: (1) it did not improve the assay performance; (2) it was an extreme pattern of PD-L1-positive inflammatory cell staining, driven predominantly by macrophages; (3) PDL1 is expressed in macrophages of normal tissue; and (4) the presence of true tumor-infiltrating lymphocytes is low.
Cell staining combined with computer-enhanced reconstructions of neurons showed that the schizophrenia group had a much lower density of projections from neurons in a specific tissue layer of the frontal cortex, the scientists report in the January ARCHIVES Or GENERAL PSYCHIATRY.
The preclinical data to be presented includes in vitro mechanism of action, immunofluorescent cell staining, in vivo anti-tumor efficacy, bio-distribution, and toxicokinetic studies.
If tumor cell staining was clearly present, that staining was captured in the MHS value.
