In Vitro Expression And Purification Of Class I Mhc Molecules, Loi Cheng
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 (β2m). …

Seeds developing within a locular space inside hollow fruit experience chronic exposure to a unique gaseous environment. Using two pepper cultivars, `Triton' (sweet) and `PI 140367' (hot), we investigated how the development of seeds is affected by the gases surrounding them. The atmospheric composition of the seed environment was characterized during development by analysis of samples withdrawn from the fruit locule with a gas-tight syringe. As seed weight plateaued during development, the seed environment reached its lowest O2 concentration (19%) and highest CO2 concentration (3%). We experimentally manipulated the seed environment by passing different humidified gas mixtures through the fruit …

Dimorphic seeds of Arthrocnemum indicum (a halophytic shrub) exhibit diverse germination responses following salinity treatment and subsequent exposure to growth regulators by adjusting their physiological and biochemical processes. The present study examined the effects of 24-h and 72-h NaCl treatment on germination, germination velocity, and the associated biochemical changes in protein and RNA contents of 2 seed morphs, and compared these effects after transfer into distilled water or 10 mM thiourea solution. Treatment for 24 and 72 h in NaCl solution induced a significant reduction in the rate of germination and final percent germination of both seed morphs. No germination …
