    Sammanfattning : Production and use of metalwork in southern Scandinavia during the Bronze Age (1700-500 BC) has above all been attributed to emerging elites.

    Sammanfattning : Animals deficient in complement components C1q, C4, C3, and CR1/2 have severely impaired antibody responses. C1q is primarily activated by antibody-antigen complexes. Antigen-specific IgM in complex with an antigen is able to enhance the antibody response against that antigen. This is dependent on the ability of IgM to activate complement. LÄS MER
