Codon-optimization of HIV-1 Viral Infectivity Factor (VIF) Gene

Expression of the HIV-1 Vif protein in the absence of other viral factors such a Tat and Rev is extremely inefficient due to the presence of inhibitory sequences on its mRNA. This invention uses codon optimization to remove such inhibitory sequences without altering the amino acid sequence of the protein. The modified vif gene in the resulting pcDNA -hVIF vector is expressed under the control of the CMV promoter. In this, the protein functions as wild type and is more amendable to high-level expression in mammalian cells.

48-Position Custom Deep Well Plate For In Vitro Equilibrium Dialysis at a 1:1 Sample to Buffer Volume Ratio

CDC scientists have developed a new design for a multi-well dialysis microplate for equilibrium dialysis. The unique design accommodates a 1:1 buffer to sample ratio and provides additional room at the base of the well to enable optimal cartridge immersion and analyte diffusion. The microplate is readily adaptable into existing automated analytical systems and meets the criteria of American National Standards Institute (ANSI). The microplate is designed for measuring blood or other biological fluid samples over a wide range of sample volumes and may be used in a high throughput manner.

Astrocyte Differentiation of Neural Stem Cells with StemPro Embryonic Stem Cell Serum Free Medium for Research and Potential Therapeutic Use

This technology includes an innovative method for differentiating astrocytes from neural stem cells (NSCs). The process involves using Life Technologies StemPro embryonic stem cell serum-free medium to initially guide NSCs towards a neuronal lineage. Over a period of 28-35 days, as the cells are continually passaged, neurons gradually die off, leading to the proliferation of astrocytes. By the end of this differentiation protocol, approximately 70% of the cells exhibit markers characteristic of mature astrocytes, specifically GFAP.

MC38 B2m KO Cell Line

Summary:

The National Cancer Institute (NCI) seeks licensees for a CRISPR/Cas9-engineered MC38 B2m knockout murine colon cancer cell line that models tumor resistance to PD-1/PD-L1 checkpoint blockade caused by loss of MHC-I antigen presentation. This research tool provides an opportunity to study checkpoint-refractory tumors and evaluate alternative or combination immunotherapy strategies for cancers that evade conventional T-cell–mediated recognition.
