Isolation of IgY from the yolks of eggs by a chloroform polyethylene glycol procedure

open access: yes, 1990
By shaking a dilute suspension of egg yolk with chloroform followed by low speed centrifugation (1500 g for 30 min) the water soluble proteins which include chicken IgG (IgY) separate from the emulsion of chloroform and lipophilic substances. The IgY may

Nanotopographical cues mechanically regulate the secretion and osteoinductive potential of MSC‐derived exosomes for bone regeneration

open access: yesBMEMat, EarlyView.
A defined 700 nm low‐density nanotopographical interface mechanically primes MSCs through the integrin β1–focal adhesion–Akt–Rab27a‐dependent pathway, enhancing exosome secretion and osteoinductive potency. Enrichment of miR‐548d‐5p in these exosomes promotes osteogenic differentiation and bone regeneration, establishing nanotopography‐guided MSC ...

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

open access: yesBiotechnology 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 Coking‐Tolerant Perovskite Catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 for Efficient Methane Dry Reforming

open access: yesCarbon and Hydrogen, EarlyView.
A new perovskite‐type catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 was developed for methane dry reforming, which exhibited 93.1% CH4 and 94.7% CO2 conversion with 100 h stability run and excellent anti‐coking capability, benefited from in situ exsolved Fe‐Ni alloy nanoparticles. ABSTRACT Perovskite with high temperature stability and tunability is a very promising

Respiratory Inhibition in Chlorella Produced by "Purified" Polyethylene Glycol 1540

open access: yes, 1968
Polyethylene glycol 1540, added to culture solution in amounts sufficient to reduce the water potential to -10 atmospheres, inhibited respiration in Chlorella much more than mannitol solutions at -10 atmospheres. This occurred despite the purification of
