Separation of Nucleic Acids by Ion Pair Reversed Phase High Performance Liquid Chromatography (IP RP HPLC) [PDF]

open access: yes, 2019
Ion-pair reversed-phase high performance liquid chromatography (IP RP HPLC) is shown to be an effective method to reliably analyze DNA. IP RP HPLC is a much faster and safer alternative to conventional methods of DNA separation and quantification.

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

open access: yesAdvanced NanoBiomed Research, EarlyView.
Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

Human Leukocyte Elastase Triggered Nanoparticles for Targeted Antimicrobial Delivery and Oral Microbial Modulation

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity

A Non-Covalent Antibody Complex for the Delivery of anti-cancer drugs [PDF]

open access: yes, 2019
Antibody drug conjugates (ADCs), which are obtained by coupling a potent cytotoxic agent to a monoclonal antibody (mAb), are traditionally bound in a random way to lysine or cysteine residues, with the final product's heterogeneity having an important ...

Nano‐Gs‐Protein Peptidomimetika: Rationales Design von Peptiden, die vom C‐Terminus von Gα abgeleitet sind und Schlüsselkomponenten der Gs‐β2AR‐Wechselwirkungen nachahmen

open access: yesAngewandte Chemie, EarlyView.
G Protein‐gekoppelte Rezeptoren (GPCRs) sind wichtige therapeutische Zielstrukturen. Die Modulation der GPCR‐Aktivität über intrazelluläre Bindungsstellen gewinnt zunehmend an Bedeutung. Ein strukturell und computergestützter Ansatz ermöglichte die Entwicklung kleiner, vom G Protein abgeleiteter Peptidomimetika, die gezielt an die intrazelluläre ...

Developing an Analytical Method for Separating and Quantifying RNA Generated in In Vitro Transcription Reactions [PDF]

open access: yes, 2015
The generation of run-off transcripts from in vitro transcription reactions is a useful technique in the study of transcription regulation. There are currently limited ways in which these run-off transcripts can be analyzed, and few that are truly ...

The abundances of hydrocarbon functional groups in the interstellar medium inferred from laboratory spectra of hydrogenated and methylated polycyclic aromatic hydrocarbons

open access: yes, 2013
Infrared (IR) absorption spectra of individual polycyclic aromatic hydrocarbons (PAHs) containing methyl (-CH3), methylene (>CH2), or diamond-like *CH groups and IR spectra of mixtures of methylated and hydrogenated PAHs prepared by gas phase ...

Novel Method to Process Cystic Fibrosis Sputum for Determination of Oxidative State [PDF]

open access: yes, 2010
Background: Induced sputum is the most commonly used method to analyze airway inflammation in cystic fibrosis (CF) patients ex vivo. Due to the complex matrix of the sample material, precise and reliable analysis of sputum constituents depends critically

A simple method to increase sensitivity for RP‐HPLC phytoplankton pigment analysis [PDF]

open access: yesLimnology and Oceanography: Methods, 2014
HPLC analysis of phytoplankton pigments from natural samples usually requires the filtration of relatively large volumes of water (1–12 L) through filters of 25–47 mm diameter. Pigment extraction from filters of this size is performed with minimum volumes of 2‐5 mL extraction solvent, routinely 90% acetone.

Photocaged Oxytocin and Vasopressin Probes to Decipher Neuropeptide Signalling With High Spatiotemporal Resolution

open access: yesAngewandte Chemie International Edition, EarlyView.
Novel and biocompatible photoactivatable oxytocin and vasopressin probes, utilising state‐of‐the‐art photocages, remain inactive in the dark. Light exposure facilitates rapid spatiotemporal receptor activation and phospholipase C (PLC)‐mediated downstream signalling. Figure created in https://BioRender.com.
