Secretion Technology
|
| |
 |
China patent
Purer Products: Secretion of the proteins out of E.coli cells can minimize the contamination by E.coli toxic proteins
Higher biological activity: Secretion can lead to products with the correct primary amino acid structure as well as 3-dimensional structures, contrary to the traditional inclusion body technology
Higher yield: no refolding is required
|
GenSci uses a procedure called secretion technology which produces 191 amino acid sequence human growth hormone, with far less E.coli protein contamination and no side effects associated with injection, such as red painful welts. Growth hormone produced using secretion technology is very stable:
before reconstituted:
if refrigerated between 2 - 8 degrees celsius it's good for over a year (untill expiration date)
at room temperature (up to 37 degrees celsius) it's good for over 30 days
at up to 45 degrees celsius it's good for about a week
after reconstituted:
it has to be refrigerated at all times. It's good for 20 days
