| Unit definition | Classical Pathway Activity: One C1qH50 unit measured by classical pathway activation is defined as the amount of C1q required to yield 50% lysis of 3 x 107 EA when incubated in the presence of the recommended volume of C1q-Dpl for 30 min at 37°C in a total reaction volume of 500 µl GVB++. CH50 Functional Activity upon Reconstitution: One CH50 unit is defined as the input of C1q-Dpl, reconstituted with C1q, or NHS Complement Standard yielding 50% lysis of 1 x 108 EA when incubated for 60 min at 37°C in a total reaction volume of 1.5 ml GVB++. Alternative Pathway Activity: One unit of whole alternative pathway activity (APH50) is defined as the input of C1q-Dpl or NHS Complement Standard yielding 50% lysis of 1.5 x 107 rabbit erythrocytes when incubated for 30 min at 37°C in a total reaction volume of 75 ml GVB° containing a final Mg-EGTA concentration of 13.3 mM. | ||
