  • Applications
    IHC-P (cell pellet)
  • Species
    SARS Coronavirus 2
Summary
Block size is 2.2 x 2.2 x 0.5 cm (expected to yield ~40-50 sections of ~4-5 μm thickness), but can vary slightly. Cell pellet consists of 293T cells overexpressing SARS-CoV-2 spike (S2 subunit) (C-terminal His-tagged) protein fixed with 4% PFA (15 min, room temp) 48 hrs post-transfection, and then embedded in paraffin. Please see the corresponding overexpression cell lysate  (GTX535662).
