The aim of this work was to develop a quick method for analysis of macromolecules of the extracellular matrix. Of great interest are soluble components of the extracellular matrix, in particular, carrier proteins, whose variation dynamics can characterize the studied tissue in its development, adult stage, and aging. We suggest the method of analysis of the(More)
The dynamics of the content albumin and carotenoids in human fetal vitreous body during weeks 16–31 of gestation was studied. The maximum values of total albumin (1.42 mg) and carotenoids (276 ng) during the studied period were recorded on weeks 20–22. Albumin concentration peaked during week 17 (2.11×10−4 mol/liter) and carotenoids during weeks 16–17(More)
Carotenoids were found for the first time in the vitreous body of human eye during the fetal period from week 15 until week 28. Their maximum content was timed to week 16–22. No carotenoids were found the vitreous body of 31-week fetuses, as well as adult humans, which corresponds to the published data. It was shown using HPLC that chromatographic(More)

Noncovalent interactions of intraionic squarylium dyes, derivatives of 3H-indolium, as well as the structurally analogous ionic indodicarbocyanine dye with serum albumins (human, bovine, rat) and, for comparison, with ovalbumin has been studied by spectral and fluorescent methods. The hydrophilic squarylium dye with sulfonate groups was found to interact(More)
Non-covalent interactions between polymethine dyes of various types (cationic and anionic thiacarbocyanines as well as anionic oxonols and tetracyanopolymethines) and human serum albumin (HSA) were studied by means of absorption, fluorescence and circular dichroism (CD) spectroscopies. Complexation with the protein leads to a red shift of the dye absorption(More)

This study aimed to analyze the aqueous humor (AH) and the vitreous body (VB) of the eye of the adult frog Rana temporaria L. as a representative species of amphibians, which lead a semi-terrestrial life. The presence of collagen, albumin, uric acid and electron donors was shown in both media; however, there are slight differences in their concentrations.(More)
The development of the vitreous body in vertebrates, including humans, is being intensely studied with the use of biochemical, histochemical, and electron microscopic methods [1–5]. The time of appearance and the localization of individual components of the vitreous body, including hyaluronic acid, glycosaminoglycans, and collagens, are paid most attention.(More)
