dc.description.abstractThe interaction between progesterone and human serum albumin has been investigated. This interaction was studied by UV-absorption and fluorescence spectroscopy. From spectral analysis progesterone showed a strong ability to quench the intrinsic fluorescence of HSA through a static quenching procedure. The binding constant (K) is estimated 6.56×102 M-1 at 293 K. FT-IR spectroscopy with Fourier self-deconvolution technique was used to determine HSA secondary structure and progesterone binding mechanisms. The observed spectral changes indicate the formation of H-bonding between progesterone and HSA molecules which can be related to the intensity decrease in the absorption band of α-helix relative to that of β-sheets.en_US

    The biophysics lab has been established at Al-Quds University in 2005 with a generous fund from the DFG of the Federal Republic of Germany. The lab has supported several research students in the fields of physics and biology; several of whom are currently finishing their Doctorates degrees in Germany and the U.S. The research lab provides services to students and faculty members in the physics, biology, chemistry, and environmental science programs, in addition to an open cooperation with the college of medicine, pharmacy and the Nanotechnology center.
