A genetic approach based on the activation of interferon-regulated-factor-1 (IRF-1) has been applied to arrest BHK cell growth in spinner flasks through the presence of estradiol in the culture medium, leading to the activation of the constitutively

Activation of the constitutively expressed interferon-regulatory-factor-1/estrogen receptor fusion protein (IRF-1-hER) in BHK cells was accomplished through the addition of estradiol to the culture medium, which enabled IRF-1 to gain its transcriptio

The aim of this work was the optimisation of a fed-batch culture by metabolic confinement of BHK21 cells producing an antibody/cytokine fusion protein with potential application in tumour-targeted therapy. Previous results showed that at very low nut

The influence of surface growth (two-dimensional microcarriers) and three-dimensional growth (aggregates and macroporous supports) in agitated, suspended batch culture systems upon growth and productivity of BHK was compared. Cultures using three por

BHK-21 cells expressing a human IgG-IL2 fusion protein, with potential application in tumor-targeted therapy, were grown under different nutrient conditions in a continuous system for a time period of 80 days. At very low-glucose (< 0.5 mM) or glutam

This work aimed at the characterisation and downstream processing of HIV-1 core and virus-like particles (CLPs and VLPs) produced in serum free medium. The produced core and virus-like particles have similar characteristics to those of the native imm

In this work the proteolytic activity in the supernatant and inside insect cells in culture was evaluated for different multiplicities of infection (MOI) and times of infection (TOI). Several methods to detect proteolytic activity in insect cells wer

Recombinant fusion proteins offer important new therapeutic approaches for the future. This report describes the use of three different genetic strategies (i.e. “mono-”, “bi-” and “tri-cistronic” vectors) to achieve stable secretion from

In this work, a BHK21 clone producing a recombinant antibody/cytokine fusion protein was used to study the dependence of cell metabolism on the glucose and glutamine levels in the culture medium. Results obtained indicate that both glucose and glutam
