Abstract

Social analysis of transplant organ demand often focuses on either small-scale (familial) tyrannies of the gift or large-scale (global) markets. Media accounts of the scandalous in transplant medicine stress the latter, a homogeneous model of flows of biovalue down gradients of economic and social capital. This article examines particular globalizations of tissue demand organized as much around claims of social similarity as gradients of social difference. To engage apparent ‘diasporic’ networks of organ purchase — Non-Resident Indians traveling to India and Overseas Chinese to China — I elaborate a concept of bodily supplementarity. Supplementarity in this account is the ability of an individual or population to secure longevity through the mobilization or acquisition of the organic form of others. Diasporic tissue circuits are analyzed in the context of ‘experiments’ in supplementarity that proliferate with the transformation of the molecular conditions for supplementarity. The emergence of powerful immunosuppressants renders the scale of tissue recruitment flexible and contingent, and allows clinics to develop alternatives to brain death. These circuits emerge as situations that reorder the relation of the familial and the global in transplantation, in the service not only of migrant supplementarity but also efforts to reimagine the challenges of emigrant belonging within particular configurations of racialized life and its government.
