title: Apolipoproteins and lipoprotein families in chicken embryos and egg yolk.
abstract: 1. Turkey anti-LP-A and anti-LP-B cross react strongly with whole adult chicken serum. 2. Similar reactions occur with whole chicken embryo sera (10-21 days of incubation) and egg yolk fluid. 3. Ultracentrifugation of sera from 14-day old chicken embryos, after reaction with anti-LP-B, reveal complete precipitation of the VLDL and LDL of embryo serum (indicating that adult-type LP-B is the major apolipoprotein of these density classes). 4. All of the chicken embryo adult-type apo-LP-A is in the HDL fraction. 5. However, egg yolk and hen serum VLDL contain apo-LP-A as well as apo-LP-B.
