Objective Objective To isolate and sequence Aedes albopictus β-actin gene and test its applicability as an internal control in gene expression studies.Methods Primers were designed based on the conserved nucleotide sequences of insect β-actin genes.A fragment of Ae.albopictus β-actin gene was amplified from the cDNA of C6/36 cells.The expression levels of Ae.albopictus β-actin in RPS4 gene stably transfected and control vector transfected C6/36 cells were both detected by RT-PCR. Results A fragment of 911 b...
