What are the optimal protocols for using BGLU17 antibodies in immunofluorescence studies?

When conducting immunofluorescence studies with BGLU17 antibodies, researchers should consider the following methodological approaches:

  • A transition point (t_stop) between the two production phases

• Model equation:
  The simplified discrete mechanistic model can be represented as:

  $Ab_{t+1} = Ab_t \times (1-r) + AbPr_t$

  Where:

  • $Ab_t$ represents antibody level at time t

  • $r$ is the clearance rate

  • $AbPr_t$ is the production rate at time t

• Parameter estimation:

  • Production rates are scaled relative to assay units

  • AbPr1 sets the scale of model output
