The M2-1 protein of respiratory syncytial virus (RSV) is a transcription processivity factor that is essential for virus replication. The function of RSV M2-1 protein can be examined by using an RSVlacZ minigenome assay in vitro since the expression of the lacZ gene is dependent on M2-1. The M2-1 protein of pneumonia virus of mice (PVM), also a member of the Pneumovirus genus, functions poorly ...

We expressed the M2 gene in prokaryotic cells using the pAED4 expression vector system to produce native and purified M2 protein as a candidate for universal recombinant vaccine against influenza A subtypes. The open reading frame (ORF) of avian influenza A/chicken/Iran/101/1998 (H9N2) M2 gene was amplified by 2-step RT-PCR using specific primers and pfu DNA polymerase. pAED4 was used as expres...

in order to evaluate the variation of some of quantitative and qualitative traits of different varieties of linseed under different plant densities, an experiment was conducted in the research station of the faculty of agriculture in shahrekord univerity in 2009. this experiment was arranged as factorial in rcbd design with three replications. four linseeds originated from australia, canada, fr...
