Analytical chemistry, 63(4), 384-390 (1991-02-25)
Surfactant-containing eluents are evaluated for possible application to direct serum injection using conventional reverse-phase columns. Serum albumin was quantitatively eluted at the column void volume by using surfactant concentrations below or above the critical micelle concentration, and organic solvents could

During virus infection and autoimmune disease, inflammatory dendritic cells (iDCs) differentiate from blood monocytes and infiltrate infected tissue. Following acute infection with hepatotropic viruses, iDCs are essential for re-stimulating virus-specific CD8(+) T cells and therefore contribute to virus control. Here
