Dynamics of Serum Binding of Intravenously Administered 57 Co Vitamin B 12 1

Summary

Following intravenous injection of ⁵⁷Co vitamin B₁₂, clearance rates of en-dogenously labeled TCII and TCI were delayed in patients with C.M.L., compared to normal subjects and cases of P.A. If ⁵⁷Co B₁₂ from TCII reappeared bound to TCI, it occurred at a rate slower than that of plasma disappearance of ⁵⁷Co B₁₂ bound to TCI.
