摘要: We developed an aqueous spreading procedure that permits simultaneous analysis of human chromosomes by Q-banding and indirect immunofluorescence. Using this methodology anticentromere antibodies from autoimmune patient we compared the active inactive centromeres isodicentric X chromosome. show a family structurally related centromere proteins (CENP-A, CENP-B, CENP-C) is detectable only at centromere. These antigens therefore may be regarded both as morphological functional markers for centromeres.
