...Martin E. Feigenson; Marco Baggiolini Human polymorphonuclear leukocytes (PMNs) were incubated at 0 °C with ferritin-conjugated ricin and warmed to 37 °C to induce capping of the ricin-binding sites. The PMNs were then allowed to phagocytose yeast or Staphylococcus epidermidis for 15 min...

...P.H.G. Hogeman; A.J.P. Veerman; D.R. Huismans; C.H. van Zantwijk; P.D. Bezemer Capping of leukemic cells with a monoclonal antibody against HLA ABC determinants was studied in 53 cases of childhood acute lymphoblastic leukemia (ALL). Determination of the percentages of capped cells after different...

...P.H.G. Hogeman; A.J.P. Veerman; E. Philippus; D.R. Huismans; C.H. van.Zantwijk; P.D. Bezemer The density of HLA determinants on the cell surface was studied in relation to HLA capping in childhood acute lymphoblastic leukemia (ALL). Analysis was performed with flow cytometry (FACS) and a subjective...

...P.H.G. Hogeman; A.J.P. Veerman; D.R. Huismans; P.D. Bezemer Capping with concanavalin A (ConA) and monoclonal anti-HLA-ABC backbone was studied in childhood acute lymphoblastic leukemia (ALL). Capping with ConA and HLA gave quite different results, both in common ALL and T-ALL. With ConA most cases...
