Cytochemical visualization of calcium binding to the plasma membrane of L-1210 lymphoid leukaemic cells.
In L-1210 lymphoid leukaemic cells fixed in glutardialdehyde supplemented with CaCl2, calcium-dependent electron dense deposits were detected. The deposits were observed on the extra-cellular surface and were nonfrequent. Abundant deposits were also found at the periphery of lipid globules. The formation of deposits and the possible physiological significance of these findings are discussed.
