Hamster Model of Leptospirosis [PDF]

Current Protocols in Microbiology, 2006
AbstractThis unit describes the techniques involved in the hamster model of leptospirosis. Hamsters are exquisitely susceptible to infection with pathogenic Leptospira species. The LD50 of virulent Leptospiral strains by intraperitoneal inoculation of 3‐ to 4‐week‐old hamsters is as low as a single organism.

One‐Pot Synthesis of a Small Synthetic Ligand for Antibody Purification

Biotechnology and Bioengineering, EarlyView.
One‐pot liquid‐phase synthesis of the synthetic ligand B1Al2A2 enables controllable ligand density and efficient capture of IgG and IgY with high recovery and purity, streamlining small‐ligand affinity purification workflows. ABSTRACT The development of synthetic affinity ligands offers a cost‐effective alternative to traditional biological ligands ...

Continuous Purification of mRNA Produced by In Vitro Transcription Using High Performance Countercurrent Membrane Purification

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Messenger ribonucleic acid (mRNA) therapeutics produced by in vitro transcription must be purified to remove residual enzymes and free nucleotides. This study examines the use of high‐performance countercurrent membrane purification (HPCMP) for the purification of mRNA therapeutics based on differences in the rate of diffusion across ...

What Makes an “Ideal” Cell Line for Recombinant Adeno‐Associated Virus Production?

Biotechnology and Bioengineering, EarlyView.
Several host cell types have been used to produce rAAVs to date. Cell line‐specific traits that are beneficial in the context of rAAV manufacturing are reviewed here, with the goal of developing a consensus on the ‘ideal’ characteristics that an rAAV production host should possess (created with Biorender.com).

Model‐Enabled Knowledge Transfer Across Cell Lines, Culture Scales and Conditions

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Mechanistic models are central to quantitative understanding and optimization of Chinese hamster ovary (CHO) cell culture processes, but their utility is often restricted by parameter sets calibrated for specific cell lines, scales, or operating conditions.

Glycoengineered Recombinant Alpha1‐Antitrypsin Results in Comparable In Vitro and In Vivo Activities to Human Plasma‐Derived Protein

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Alpha‐1‐antitrypsin (A1AT) is a multifunctional, clinically important, high‐value therapeutic glycoprotein that can be used for the treatment of many diseases, such as A1AT deficiency, diabetes, graft‐versus‐host disease, cystic fibrosis, and various viral infections. Currently, the only U.S. food and drug administration‐approved treatment for

Neutralizing gut-derived lipopolysaccharide as a novel therapeutic strategy for severe leptospirosis

eLife
Leptospirosis is an emerging infectious disease caused by pathogenic Leptospira spp. Humans and some mammals can develop severe forms of leptospirosis accompanied by a dysregulated inflammatory response, which often results in death.

Metabolic Flux Analysis Reveals Cell Line‐Specific Rewiring in CHO Cells Following TCA Cycle Intermediate Feeding for Bioprocess pH Control

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Chinese hamster ovary (CHO) cells are the leading host for recombinant therapeutic protein production in the biopharma industry. In this study, we investigated how feeding acidic forms of tricarboxylic acid (TCA) cycle intermediates—malic acid, succinic acid, and α‐ketoglutaric acid—affects cell culture performance and metabolism in two ...

Translating Blue Light Stimulation From Batch to Perfusion: Process and Intracellular Metabolic Analysis

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Improving cell‐specific productivity remains a central objective in biopharmaceutical manufacturing. In this study, the effect of blue light illumination on IgG1‐producing CHO DP‐12 cells was systematically evaluated across batch, fed‐batch, and perfusion cultivations in controlled 3 L bioreactor systems.
