Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

open access: yesAdvanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Chemiluminescence detection of gangliosides by thin-layer chromatography.

open access: yesJournal of Lipid Research, 1995
We describe a method for the detection of gangliosides on thin-layer chromatography plates using enhanced chemiluminescence. In contrast to previously published colorimetric techniques, the use of chemiluminescence of detect antibody binding to ...

Preparative thin-layer and column chromatography of prostaglandins

open access: yesJournal of Lipid Research, 1969
Analytical and preparative chromatographic methods for monounsaturated prostaglandins are described. The systems were developed specifically for separation of the various hydroxy epimers of prostaglandin E1 and F1 but also offer superior separations for ...
