relationship between biotin-binding proteins from chicken plasma and egg yolk.the plasma of laying hens contains a specific biotin-binding protein that appears to be identical with an egg-yolk biotin-binding protein. both proteins are saturated with biotin and require elevated temperatures to effect the exchange of [14c]biotin for the protein-bound vitamin. the heat-exchange curve in each case is the same and differs sharply from that of avidin, the egg-white biotin-binding protein. on sephadex g-100 gel filtration, plasma and yolk biotin-binding proteins were each eluted ...1978105724
drosophila melanogaster lacks eye-pigment binding proteins.drosophila melanogaster contains no detectable eye-pigment binding proteins, and the previous evidence for the presence of such protein in the cecropia moth is probably not valid. the major brown pigment of drosophila (and of cecropia), dihydroxanthommatin, behaves as a high molecular weight compound in sephadex chromatography, thus leading to false conclusions.1998105753
mutual homology of mouse immunoglobulin gamma-chain gene sequences.we have assessed the relative homology of mouse immunoglobulin heavy-chain gene sequence using complementary dnas (cdnas) synthesized against gamma-chain mrnas (gamma 1, gamma 2a, gamma 2b, and gamma 3) purified from mouse myelomas. cdnas complementary to the gamma-chain mrnas did not cross-hybridize with the mu- and alpha-chain mrnas, whereas they cross-hybridized to significant extents (22--66%) with the gamma-chain mrnas of other subclasses. the heterologous hybrids formed, however, melt at 5 ...1979105754

multiple sclerosis: immunochemical studies on the demyelinating serum factor.sera from patients with multiple sclerosis (ms) frequently produce demyelination of central nervous system tissue cultures. the nature of the factors responsible for demyelination is not as yet clearly established. however, several authors previously reported, in in vivo and in vitro models, demyelinating activity in igg fractions isolated from sera and cerebrospinal fluid of ms patients14,42,48. we found the demyelinating activity of ms sera to be extremely labile to conventional biochemical tr ...1979105780
