The chimeric proteins viz. CBM3-Cel9A, CBM4-Cel9A and CBM30-Cel9A, are constructed by fusion of family 3, 4, and 30 cellulose binding modules (CBMs) to N-terminus of family 9 endoglucanase (Cel9A) from Alicyclobacillus acidocaldrious. The chimeric enzymes were successfully expressed in Escherichia coli and purified to homogeneity. The chimeric enzymes showed significant increase in Avicel (8-12...

A chimeric protein (N-PYP-Hla), consisting of staphylococcal pore-forming toxin α-hemolysin (Hla) and photoactive yellow protein (PYP), exhibited photoresponsive hemolytic activities, where visible light irradiation gave rise to retardation of hemolysis at 25 °C.

Mucosa-associated lymphoid tissue (MALT) lymphoma is a common type of lymphoma in extranodal sites. The most frequent chromosome translocation associated with MALT lymphoma is t(11;18)(q21;q21), which generates a chimeric protein of c-IAP2 and MALT1/paracaspase. The c-IAP2/MALT1 fusion protein activates the NF-kappaB pathway, which is considered critical to malignant B cell transformation and l...

Phage display is a technique that involves the coupling of phenotype to genotype in a selectable format. It has been extensively used in molecular biology to study protein-protein interactions, receptor and antibody binding sites, and immune responses; to modify protein properties; and to select antibodies against a wide range of different antigens. In the format most often used, a polypeptide ...

A genetic fusion between streptavidin of Streptomyces avidinii and luciferase of Pyrophorus plagiophthalamus was constructed. The fusion protein was produced in the Sf9 insect cell line using the baculovirus expression vector system (BEVS). Sodium dodecyl sulfate polyacrylamide gel electrophoresis of the proteins from cells infected with the recombinant virus, VL1393-LucGR-StreptAv, revealed th...

radioimmunotherapy (rit) of non-hodgkin’s lymphoma (nhl) is said to be more advantageous compared to unlabelled therapeutic antibodies. to this date, radiolabelled murine anti-cd20 mabs, zevalin® and bexxar® have been approved for imaging and therapy. a preparation containing rituximab, chimeric mab radioimmunoconjugate suitable for lu-177 labeling, could provide better imaging and therapeutic ...
