Cloned (Comment) Organism
recombinant expression of active chimeric mutant of tissue plasminogen activator in Nicotiana tabacum hairy roots Homo sapiens

Protein Variants

Protein Variants Comment Organism
additional information the activity of tPA is increased by splicing the active site of dodder-cuscutain gene to human tPA. The chimeric cDNA of tPA is constructed through splicing by overlap extension PCR (SOEing-PCR) method and transferred to the hairy roots of tobacco using different strains of Agrobacterium rhizogenes. Agrobacterium rhizogenes strain ATCC 15834 is the most favorable strain for the induction of hairy roots in tobacco, overview Homo sapiens

Purification (Commentary)

Purification (Comment) Organism
recombinant chimeric tissue plasminogen activator mutant from Nicotiana tabacum hairy roots by lysine affinity chromatography. In addition, specific aptamers are designed using SELEX method. Multi wall carbon nanotubes are functionalized with selected aptamers, Chi-tPA1-5, packed in a column, and used for purification. The selected aptamer Chi-tPA1, having KD values of 0.320 nM and IC50 of 28.9 nM, possesses good affinity to tPA, and the chimeric mutant tPA is properly purified by aptamer-chromatography. Development of aptamer-based affinity purification method, overview Homo sapiens
