Expression and purification of 15kDa granulysin utilizing an insect cell secretion system

Cloning and Expression of Simian Rotavirus Spike Protein (VP4) in Insect Cells by Baculovirus Expression System

Background: VP4 protein is as spikes on rotavirus outer capsid shell which is responsible for virus attachment to the host. VP4 induces production of neutralizing antibodies which could be used for serotyping of different isolates. Methods: Simian rotavirus SA11 gene 4 cDNA was cloned into a cloning plasmid pDONRTM by recombination reaction using clonase II enzyme mix. The resulting clone was c...

Codon Usage in Signal Sequences Affects Protein Expression and Secretion Using Baculovirus/Insect Cell Expression System.

By introducing synonymous mutations into the coding sequences of GP64sp and FibHsp signal peptides, the influences of mRNA secondary structure and codon usage of signal sequences on protein expression and secretion were investigated using baculovirus/insect cell expression system. The results showed that mRNA structural stability of the signal sequences was not correlated with the protein produ...

expression of the recombinant plasminogen activator (reteplase) by a non-lytic insect cell expression system

reteplase is a potent thrombolytic agent which is widely used in the management of acute myocardial infarction and stroke. it belongs to the third generation of the thrombolytic drugs and has been derived from native human tissue plasminogen activator by removing three domains of it and keeping the kringle 2 and serine protease domains. however, the high cost of this drug, has limited the appli...

Expression and Purification of Homeodomain

Homeobox genes encode transcription factors which play important roles in the developmental processes of many multicellular organisms. TGIFLX/Y (TGIFLX and TGIFLY) are members of the homeobox superfamily of genes. Their expressions are specifically detected in the human adult testis but their functions are remained to be investigated. In this investigation we cloned full length of TGIFLY cDNA a...
