nonGMP Monoclonal Antibody / Protein Production

MassBiologics provides nonGMP antibody and protein expression in mammalian cell culture.  Cell culture can be performed in shake flasks, wave bags, 1L, 10L or 60L stirred tank bioreactors.  We routinely manufacture materials at scales from a few milligrams to 10s of grams.  We have developed several standardized programs that address our most commonly requested services.  If the programs below do not meet your needs, please contact us and we will gladly design a program for your specific application.

Small scale antibody production from transduced cell pools with client supplied DNA for antibody gene sequences. 

Included services:

  • Cloning of antibody into vectors
  • Large scale production of plasmids
  • Electroporation of plasmids into MBL2 CHO cells / cell incubation (40 x 96 well plates)
  • Pool selection: 1st round performed in 96 well plates (~250 mini-pools)
  • Pool selection: 2nd round performed in shake flasks (~10 mini-pools)
  • Scale up of top pool to seed 10L bioreactor
  • Production in 10L bioreactor ≤ 5g (pool expected to yield 0.5 g/L)
  • Purification by Protein A, buffer exchange into PBS, SDS-PAGE, A280 & bioburden analysis

Generation of stable clones with client provided DNA.
