Title:
Developability Package 3

Description:
Developability Assessment – Package 3

Scope:

Formulation and Stability Testing Package Workflow

  • Buffer formulations
  • Stress Conditions
  • Assays

Task 1. Buffer Formulations

A total of six (6) buffer formulations will be chosen. Curia has a standard panel of formulations ranging from pH 5 – 7

that were chosen based on common formulations used for commercial antibodies. Client may opt to choose their own

buffers for testing. Special/custom reagents and buffers may be charged to client as material costs.

Task 2. Stress Conditions

The protein will be subjected to a total of three (3) conditions. The protein will also be characterized immediately after

buffer exchange.

  • After buffer exchange (T0)
  • No-stress: storage at 4°C for 28 days.
  • Thermal stress: incubation at 40°C for 28 days
  • Freeze/thaw stability: 5 cycles of freeze/thaw

In addition, an aliquot from each stress condition will be sent to the client for binding and/or functional testing.

Task 3. Assays

The protein will be characterized by the following assays immediately after each specified condition:

  • Thermostability analysis by DSF/DLS using UNcle
    • Only 2 conditions: before buffer exchange, after buffer exchange
  • Post-translation modification by mass spectrometry
    • All 5 conditions: before buffer exchange, after buffer exchange, no-stress, thermal, freeze/thaw
  • Aggregation analysis by SE-UPLC
    • All 5 conditions: before buffer exchange, after buffer exchange, no-stress, thermal, freeze/thaw
  • Purity analysis by CE-SDS (R/NR)
    • All 5 conditions: before buffer exchange, after buffer exchange, no-stress, thermal, freeze/thaw
  • Charge variant analysis by cIEF
    • All 5 conditions: before buffer exchange, after buffer exchange, no-stress, thermal, freeze/thaw
