Onë-step preparation of the polypeptide chains of a-crystallin

One-step preparation of the polypeptide chains of -crystallin.

The effect of calcium upon the reaggregation of bovine alpha crystallin.

Calcium is capable of discriminating between low and high molecular weight species of bovine alpha crystallin. If native alpha crystallin of molecular weight 15 x 10 or greater is deaggregated in 7M urea and then reaggregated by removal of the dissociating agent only low molecular tceight aggregates are obtained. However, in the presence of calcium, reaggregation of the subunits to species of 5...

THE STRUCTURE OF THE ACIDIC POLYPEPTIDE CHAINS FROM a-CRYSTALLIN. AMINO ACID COMPOSITION, PEPTIDE MAPPING, AND N-TERMINUS

Sonochemical Synthesis of Ca(OH)2 Nanoparticles and Its Application in Preparation of MWCNT-Paraloid Nanocomposite

In this work at the first step calcium hydroxide nano-particles were synthesized via sono-chemical method at room temperature. At the second step aminated multi-walled carbon nano-tubes was prepared via chemical modification of surfaces of CNT. Finally modified-MWCNT and Ca(OH)2 were added to paraloid matrix by aid of ultrasonic irradiation. Paraloid-modified-MWCNT-Ca(OH)2...

Brdtain N - Terminal Sequences of a - Crystallin

The amino acid sequences at the N-terminal ends of the chains of the lens protein, a-crystallin, were studied. Both the main kinds of chain in bovine ix-crystallin (A chains and B chains) have an N-terininal methionine residue, and the amino group is acetylated. Selective purification of the peptides in a tryptic digest of bovirne a-crystallin gave a preparation consisting largely of the N-term...
