Comparison of fractional catabolic rates and compartmental distributions of HLA(H)₆ (this study, see Fig 8) and of RSA.36 Symbols: j_T , j₃ , and j_3.5 , fractions of fusion protein or RSA in total body, plasma compartment, and plasma compartment plus noncirculating vessel wall catabolized per day; A_p , A_w , and A_e , fractions of total body fusion protein or RSA in plasma, noncirculating vessel wall, and extravascular compartments, respectively. Data were calculated from individual plasma curves as described in Materials and Methods.
