Application of commercial ultrafiltration membranes for protein purification by high performance countercurrent membrane purification (HPCMP)

Biotechnology Progress, EarlyView.
Abstract High performance countercurrent membrane purification (HPCMP) has emerged as a promising diffusive separation strategy for the purification of recombinant proteins and monoclonal antibodies (mAbs). However, prior studies employed dialysis membranes, which are designed for diffusive separations but have not been validated for biopharmaceutical ...

Small scale purification and biophysical characterization of haptoglobin derived from human Cohn fraction IV

Biotechnology Progress, EarlyView.
Abstract Haptoglobin (Hp) is a polymorphic acute phase α‐2 glycoprotein found in plasma that plays a critical role in binding, neutralizing, and removing cell‐free hemoglobin (Hb) from the circulation. Under clinical conditions characterized by high levels of hemolysis, such as in patients with sickle cell disease (SCD), large quantities of cell‐free ...

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...
