Purification Of Hepatocytes And Sinusoidal Endothelial Cells From Mouse Liver Perfusion, Fatima Cabral, Colton M. Miller, Katrina M. Kudrna, Blake E. Hass, Jocelyn G. Daubendiek, Brianna M. Kellar, Edward N. Harris Jan 2018

Purification Of Hepatocytes And Sinusoidal Endothelial Cells From Mouse Liver Perfusion, Fatima Cabral, Colton M. Miller, Katrina M. Kudrna, Blake E. Hass, Jocelyn G. Daubendiek, Brianna M. Kellar, Edward N. Harris

Biochemistry -- Faculty Publications

This protocol demonstrates a method for obtaining high yield and viability for mouse hepatocytes and sinusoidal endothelial cells (SECs) suitable for culturing or for obtaining cell lysates. In this protocol, the portal vein is used as the site for catheterization, rather than the vena cava, as this limits contamination of other possible cell types in the final liver preparation. No special instrumentation is required throughout the procedure. A water bath is used as a source of heat to maintain the temperature of all the buffers and solutions. A standard peristaltic pump is used to drive the fluid, and a refrigerated ...


Light-Activated Binary Nucleotide Reagent For Inactivation Of Dna Polymerase, Evan M. Cornett Jan 2012

Light-Activated Binary Nucleotide Reagent For Inactivation Of Dna Polymerase, Evan M. Cornett

Electronic Theses and Dissertations

This work explores a binary reagent approach to increase the specificity of covalent inhibitors. In this approach, two ligand analogs equipped with inert pre-reactive groups specifically bind a target biopolymer. The binding event brings the pre-reactive groups in proximity with each other. The two groups react, generating active chemical intermediates that covalently modify and inactivate the target. In the present study we compare the new approach with the traditional single-component reagent strategy using DNA polymerase from bacteriophage T4 as a model target biopolymer. We report the design and synthesis of two analogs of deoxythymidine triphosphate, a natural DNA polymerase substrate ...

In Vitro Expression And Purification Of Class I Mhc Molecules, Loi Cheng May 2006

In Vitro Expression And Purification Of Class I Mhc Molecules, Loi Cheng

Honors Scholar Theses

The major histocompatibility complex (MHC) is a gene family responsible for many critical functions of the immune system in most vertebrates. The MHC consists of three classes differentiated by their structure and function, and MHC class I encodes antigen binding proteins as well as chaperone and accessory proteins such as tapasin. The purpose of this project is to reconstitute several human MHC class I molecules in their peptide-filled and peptide-deficient forms, and to purify these proteins for biochemical study. The expressed proteins include wild type and mutant variants of the fusion protein human leukocyte antigen HLA-B*0801-fos, and human beta-2-microglobulin ...
