The modification of high-performance liquid chromatography parameters leads to a more effective oligonucleotide-A purification process. Using various experimental such as buffer, concentration, and pH, method for optimizing the an on reverse-phase C18 column was created. To purify oligonucleotide-A, High-Performance Liquid Chromatography (HPLC), Ultraviolet-Visible Spectrophotometry (UV-Vis), C...

Tilmicosin (TLM) is an important antibiotic in veterinary medicine with low bioavailability and safety. This study aimed to formulate and evaluate physicochemical properties, storage stability after lyophilization, and antibacterial activity of three TLM-loaded lipid nanoparticles (TLM-LNPs) including solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs), and lipid-core nanocap...

The effects of glass transition of, and protein conformation in, the dried solid on the storage stability of freeze-dried recombinant human interleukin-1 receptor antagonist (rhIL-1ra) were examined. Glass transition is a temperature-dependent phenomenon. Amorphous materials become hard and brittle at temperatures below their characteristic glass transition temperatures (Tg) such that diffusion...

In this work, a blend of gelatin A (GA) and polyvinylpyrrolidone (PVP K30) was used for semi-solid 3D printing bone scaffold ibuprofen (IBU) delivery. The cross-linking the obtained performed with 1% glutaraldehyde (GTA) solution, followed by lyophilization. thermal mechanical properties, as well drug release profiles, kinetics prepared scaffolds were investigated. cross-linked lyophilized has ...

Abstract Purpose Uridine diphosphate glucose pyrophosphorylase (UGPase) plays an important role in metabolism, catalyzing the reversible formation and decomposition of UDP-glucose (UDPG). In previous work, we found that UGPase is a key enzyme lyophilization response for Lactobacillus acidophilus ( L. ). However, its function regulatory mechanism freeze-drying stress are unknown. Herein, effect ...
