Web21 oct. 2016 · To further advance a subcutaneous injection of monoclonal antibodies (mAbs) at elevated concentrations, novel concepts are needed to lower the viscosity. The addition of high concentrations of cosolutes, namely, arginine glutamate (Arg·Glu) or Arg·HCl, reduced the viscosity of a ∼250 mg/mL mAb solution up to 6-fold. Web5 ian. 2015 · Partially reduced mAb subclasses were re-oxidized quickly in vitro. • The re-oxidized mAbs are fully assembled/indistinguishable from drug products. • Partially reduced mAbs are fully potent in cell-based bioassay. • These results will be very helpful to address concerns from regulatory agencies.
WebReduction of mAbs For the separation of the light and heavy chains, an aliquot of 0.5 M TCEP stock was added to the mAb samples to obtain a final concentration of 10 mM. … WebThe concentration of mAb-cysteine thiols produced was determined by titrating with DTNB, typically resulting in 4.0 to 4.5 thiols/mAb when 3.25 molar equivalents of DTT were …
Websampling the mAb peak by a time-based heart cut, the trap column was switched to the flow path of the second dimension using the 2D-LC valve. An aqueous TCEP solution enabled the reduction, while it also allowed the mAb to be retained on the reversed-phase trap column. TCEP is a reducing agent that is easily soluble and stable in aqueous solutions. WebmAb reduction and alkylation Step 1. Add 4 μL of 0.5 M DTT to mAb sample for a final concentration of 10 mM DTT and mix the sample mixture well by quick vortexing Step 2. Incubate the sample at approx.+56 °C for 45 minutes Step 3. Cool to room temperature for 10 minutes Step 4. Add 4 μL of 0.5 M IAA into the sample mixture and
WebReduction of mAb to Heavy Chain (HC) and Light Chain (LC) Subunits Reduction of inter-chain disulfides in a mAb (1 mg/mL) was achieved by incubation of mAb with 20 mM dithiothreitol (DTT) at 50 °C for 30 min. The reduced sample was acidified with formic acid to a final concentration of 0.1%.
