Fourier transformed infrared spectroscopy of human serum albumin (HSA) in the region of 650-4000cm-1 was subjected for developing reagentless measurement of HSA.
The infrared spectra were subjected to partial least squares (PLS) regression to obtain calibration models predicting the concentrations of the HSA. The calibration in the concentration of 1 - 6.5mg/dl has yielded a correlation coefficient of 0.99 and a standard error of prediction of 0.11mg/dl with latent variable of six. These result suggests that the infrared spectra of aqueous solutions of HSA and its calibration model developed using PLS regression can extract up effectively the information about albumin contained in water.
These results provide a base for development of reagentless method of measurement of HSA in human serum and also in vivo HSA measurement.
