An Improved Method for the Preparation of Type I Collagen From Skin Christina A. Pacak1,2, Allison A. MacKay1, Douglas B. Cowan1,2 1 Traditional procedures for the isolation of soluble type 1 collagen (COL1) require about 10 days from start to finish because of lengthy buffer incubations and laborious resuspensions of fibrils. Here, we describe a means to purify COL1 from small dermal biopsies in less than 3 hr.
Rapid Isolation And Purification Of Mitochondria For Transplantation By Tissue Dissociation And Differential Filtration Janine M. Preble1, Christina A. Pacak2, Hiroshi Kondo1, Allison A. MacKay2, Douglas B. Cowan2, James D. McCully1 1Division of Cardiothoracic Surgery, Beth Israel Deaconess Medical Center and Harvard Medical School, 2 A method for rapid isolation of mitochondria from mammalian tissue biopsies is described. Rat liver or skeletal muscle preparations were homogenized with a commercial tissue dissociator and mitochondria were isolated by differential filtration through nylon mesh filters. Mitochondrial isolation time is <30 min compared to 60 - 100 min using alternative methods.
