...als with the production, refolding and characterization of recombinant α-amylase (AMYSBS) from Geobacillus SBS-4S. AMYSBS exhibited a highest identity of 99.78% with Geobacillus thermoleovorance GTA. E.coli BL21-CodonPlus (DE3) cells were used as host for expression studies of AMYSBS. Recombinant AMYSBS produced as inclusion bodies was transmitted to soluble active form by denaturing the in...

...owed by denaturation and refolding through fractional dialysis with urea. Multiple alignment with other sequences showed nucleotide variations of HCV3a E2 compared with already reported sequences. A total of 140 (11%) point mutations were found in Pakistan’s gene sequence, out of which general and specific differences were 93 (9%) and 47 (4%), respectively. The general differences usually occur in common population while the specific differences are pres...

...urification of IL-2. The refolding of the purified IL-2 was achieved by stepwise dialysis method using urea gradient (8M-0M). Human IL-2 was recovered from 1 litre culture to a purity level of ~95%. In vitro cytotoxic potential of IL-2 on HepG-2 and MCF-7 cell lines revealed that it possess sufficient cytotoxic potential and can inhibit the growth of these cell lines directly. Thus, refolded IL-2 had activity identical to that of authentic IL-2 and enhan...
