Plasmids with genetic variants of CEL

— These plasmids encode carboxyl ester lipase (CEL) with and without genetic variants that are associated with chronic pancreatitis.

To make the plasmids, the researchers used a full-length human CEL cDNA clone. The cDNA encoded for a 14-repeat VNTR, the variant present in the CEL MODY family. The Ec…

Monoclonal Antibodies Against Zika Virus and Purified Zika E Protein

— To generate a panel of antibodies against ZIKV, we serially infected Irf3/ mice 30 days apart with ZIKV MR-766 (Uganda, 1947) and ZIKV H/PF/2013 (French Polynesia, 2013). Irf3/ mice were used instead of wild-type (WT) mice, because ZIKV strains are deficient in evading type I interferon-mediated imm…

Fibroblast-Derived Cell Line Producing Wnt3a, R-spondin 3, & Noggin

— Tangible Tool: Growth factor over-expressing cell line.

Notes: Produces conditioned media to grow various mammalian tissue stem cells.

These supportive L-WRN cells can produce conditioned media containing Wnt3a, R-spondin, and Noggin for the the support of gastrointestinal stem cells. This system can be used to make stem cell enriched epithelial spheroids from the mouse gastrointestine.

cryaa-R49C knock-in mice

— Knock-in mice with a mutation in alpha-crystallin (cryaa-R49C) that causes cataracts. A knock-in plasmid was generated by cloning the 5′ and 3′ arms of the mouse RAcrystallin gene, followed by mutation and homologous recombination in mouse embryonic stem cells, which were implanted into …
