Evidence will be presented that first order, spontaneous activation of solution C1 at 37 degrees C under physiological conditions is a very slow process with a half-life of the order of one day and perhaps considerably longer. In addition, negative evidence will be presented showing that the formation of functionally significant levels of a complex between(More)
We have developed a method to initiate spontaneous activation of the first component of complement in serum, by the removal of C1-inhibitor through complexation with added C1s. Preliminary experiments to test this method using C1 reconstituted from its purified subcomponents led to an unexpected result: pre-incubation of the reassembled subcomponents with(More)
Lymphoblastoid cell lines were established from female relatives of patients with congenital X-linked-agammaglobulinemia by Epstein-Barr virus transformation of their peripheral B lymphocytes. Cell lines derived from presumed carriers were characterized by low ecto-5'-nucleotidase activity and a reduced percentage of surface immunoglobulin-bearing cells.(More)
Monoclonal antibody 1H11, which binds to the "head" portion of C1q, has been shown to be a strong, stoichiometric activator of C1, the first component of human complement, maximal activation being achieved at a ratio of one antibody-combining site per one C1q head; moreover, this activation occurs even in the presence of C1-inhibitor, as reported(More)
