Production of Cross-Linked Lipase Crystals at a Preparative Scale

Cross-linked protein crystals for vaccine delivery.

The progress toward subunit vaccines has been limited by their poor immunogenicity and limited stability. To enhance the immune response, subunit vaccines universally require improved adjuvants and delivery vehicles. In the present paper, we propose the use of cross-linked protein crystals (CLPCs) as antigens. We compare the immunogenicity of CLPCs of human serum albumin with that of soluble pr...

An Automatic Refolding Apparatus for Preparative-Scale Protein Production

Protein refolding is an important process to recover active recombinant proteins from inclusion bodies. Refolding by simple dilution, dialysis and on-column refolding methods are the most common techniques reported in the literature. However, the refolding process is time-consuming and laborious due to the variability of the behavior of each protein and requires a great deal of trial-and-error ...

Enabling Thermoreversible Physically Cross-Linked Polymerized Colloidal Array Photonic Crystals.

We physically cross-linked a thermoreversible poly(vinyl alcohol) (PVA) hydrogel (TG) within a crystalline colloidal array (CCA) to form an enabling photonic crystal material. The TG consists of a physically cross-linked network formed in a process reminiscent of the well-known freeze-thaw physically cross-linking process, but which avoids solvent freezing which invariably disorders the CCA. Th...
