PEG-g-PGA, PEG 5k & PGA 1.5k

PEG-PGA is a custom synthesis reagent. PEG is grafted to Poly(Glutamic Acid). PEG MW options include 1k, 2k, 5k, 10k and 20k; and polyglutamic acid sodium salt MW includes 1,500, 7,500, 15k, 30k, 45k and 60k with corresponding number of glutamic acid repeating units of 10, 50, 100, 200, 300 and 400 respectively. The PEG to PGA ratio (# of PEG per PGA polymer molecule) could be any value from 1:1 to 50:1, depending on the MW of PGA.
