Cloning of the matrix gene of measles virus (Hallé strain).

Measles virus haemagglutinin gene: cloning, complete nucleotide sequence analysis and expression in COS cells.

A measles virus (Hallé strain) cDNA library was prepared by cloning virus-induced mRNA directly into the expression vector PCD. Clones corresponding to the measles virus haemagglutinin (HA) gene were isolated and one, PCD-HA-15, which corresponded to the complete mRNA sequence, was further characterized. After transfection into COS-7 cells, measles virus HA antigen was detected by immunofluores...

Construction of a Minigenome Rescue System for Measles Virus, AIK-c Strain

Background:In the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded RNA viruses from cDNA or viral minigenomes. This technique has been applied to study different steps in virus replication and virus-host interactions. Reverse genetics could also be implemented for design of new vaccines. The T7 RNA polymerase activity as well as virus (nucleocapsi...

Sequence Variation in Measles Virus F Gene of AIK-C Vaccines Strain after Passage in Vero Cells

Molecular Cloning and Expression of Nucleocapsid Gene of Chicken Infectious Bronchitis Virus Strain Massachusetts H120

Chicken infectious bronchitis virus (IBV) causes severe respiratory and renal dysfunction in chickens. In the present study, we used reverse transcription-polymerase chain reaction (RT-PCR) to amplify the nucleocapsid (N) protein gene of strain Massachusetts (Mass) H120 of IBV that is commonly used in the vaccine production in Iran. The PCR product with the expected size of 1.2 kb was cloned in...

Molecular cloning and recombinant expression of the VP28 (wsv421 gene) from Iranian white spot syndrome virus isolate

White spot syndrome virus (WSSV) is a highly pathogenic and prevalent virus affecting shrimp culture worldwide including Iran. In the present study, a pair of primers was designed according to the sequence of VP 28 gene of WSSV in the GenBank. VP28 gene from an Iranian WSSV isolate (IrVP28) was cloned, sequenced and expressed in Escherichia coli BL21(DE3) strain in order to produce VP28 protein...
