Purification of immunoglobulins from chicken sera by thiophilic gel chromatography.

open access: yesPoultry Science, 2007
Immunoglobulin Y is different from most of the other immunoglobulins because it does not bind protein A or protein G. Thiophilic gel chromatography has been successfully used to purify IgY from chicken egg yolk, but the technology has not previously been

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Separation of lipids by Silica Gel G column chromatography

open access: yesJournal of Lipid Research, 1964
A column chromatographic procedure utilizing Silica Gel G is described for separating lipid components of serum and lipoproteins into individual fractions containing hydrocarbons (I), cholesterol esters (II), triglycerides (III), cholesterol (IV), free ...

Versatile vector tools for efficient protein screening across multiple expression systems

open access: yesFEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

open access: yesFEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

The derivation of bioprocess understanding from mechanistic models of chromatography [PDF]

open access: yes, 2015
This thesis, completed in collaboration with Purification Process Development of Pfizer Biotherapeutics, is concerned with how mechanistic models of chromatographic bioseparations can be applied in industry to accelerate development and increase ...

Purification of rat pancreatic lipase

open access: yesJournal of Lipid Research, 1968
A procedure for the isolation of lipase (glycerolester hydrolase, EC 3.1.1.3) from rat pancreas is described. The purification scheme includes homogenization of the pancreas. centrifugation at 3,000 rpm, centrifugation at 40,000 rpm.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Production of effective antivenin to treat cobra snake (Naja naja oxiana) envenoming

open access: yesArchives of Razi Institute, 2010
Conventional treatment of Naja naja oxiana (NNO) envenoming requires large volumes of equine antivenin raised against NNO crude venom. The poor efficiency of this antivenin is assumed to be due to the high molecular weight non-toxic proteins, a strong ...
