Allele Custom Services for Drug Screening Companies

Many target discovery and validation programs can benefit from RNA interference, fluorescent proteins, stem cells, and viral delivery systems. However, applications of these technologies require special reagents and laboratory know-how. Even when available, many generic reagent kits are not tailored for your particular needs in screening or validation.

At Allele, we accelerate your discovery efforts with custom RNAi screening, fluorescence based assays, and cell model development services.

1) Our RNAi platform, based on our patented shRNA/miRNA technologies, use DNA linear template, plasmid, lentivirus, retrovirus, or baculovirus vectors that prompt cells to endogenously express RNAi. As a result, our screens offer advantages over synthetic siRNAs:
• Higher levels of consistency
• Greater delivery and gene silencing efficiencies
• Accessibility to difficult-to-transfect cells, including primary cells
• Potential for inducible RNAi expression
• More persistent silencing with shRNA under Allele’s own IP–you may not need to license siRNA patents!

2) Fluorescent proteins (FPs), which can span the entire visual spectrum, have become some of the most widely used genetically encoded tags. Genes encoding FPs alone or as fusions to a protein of interest may be introduced to cells by a number of different methods, including simple plasmid transfection or viral transduction. Allele Biotech is one of a few companies that develop and improve FPs through fundamental research. We have so far achieved:
• The brightest cyan and green FPs, true monomers for minimum artifact or cytotoxicity
• The brightest yellow and red FPs from lancelet, only FPs from vertebrate
• mTFP1 as the best FRET donor by 3 independent reports
• Photoconvertible FPs for super imaging or kinetic labeling
• Delivery on plasmid, retrovirus, lentivirus, baculovirus vectors

3) As a major advancement in the stem cell field, it has recently been shown that mouse and human differentiated cells may be reprogrammed into stem-like, pluripotent cells by the introduction of defined transcription factors. These induced stem cells (iPSCs) provide unprecedented resources of cells of different differentiation stages for functional testing and drug screening. Allele Biotech develops and provides state-of-the-art reagents in convenient forms for iPSC production
• iPS factors carried on lentivirus, retrovirus, baculovirus for different cell types
• Availability in combination with fluorescent proteins under own IP, and drug resistant genes
• 4-in-1 or 2-in-1 effective use of iPS factors on one viral vector
• Feeder cells of human origin expressing factors essential for stem cell culturing

4) Introduction of protein factors, miRNA, promoter-reporter, and virtually any other genetic element of interest via the most efficient viral packaging systems.
• Introducing protein-FP fusion, promoter-FP reporter, photoactivatable factors for cell-based assays
• Introducing critical factors for cell immortalization
• Episomal or integrated expression using baculoviral vectors
• High throughput, systematic expression of whole class of molecules in any type of cell
• High titer viral packaging at low cost for delivery to animal tissues

In addition, the Allele team can provide custom-designed assays that can be used for assaying enzyme activities in almost any pathway, such as the EGF pathway, TNF response/apoptosis pathway, nuclear receptors, etc. We utilize technically advanced methods to provide our partners with advantages over alternative methods or other services.

Effective Use of Resources in Difficult Times

In scientific research, there is a tendency to have everything done in our own lab just so that you can say so, after all, scientific credit is the core criterion researchers are evaluated on. You say wait a minute, don’t we always encourage exchange of materials and COLLABORATION on projects? Sure, but not often enough to make “encouragement” unnecessary. Many “collaborations” are more like sharing of materials with conditions.

In business, collaboration is more in the form of OUTSOURCING or CO-DEVELOPMENT (sometimes through licensing), because doing everything by one’s own employees just doesn’t make much financial sense even for the mega-sized, we-have-everything type of companies. One friend of ours working at a Johnson & Johnson site once told us that a line of research using gene silencing technologies was debated but never moved forward because the lack of confidence in expertise: we are not expert on RNAi, how do we trust our own data? For most biotech and early-stage pharma companies, hiring an expert to do a task brings about too much uncertainty, not to mention cost efficiency.

“Having the expert do it” by outsourcing is somewhat more acceptable to the industry than the academia because the “We are the experts” mentality is more dominant in the latter. Heck, if we don’t believe “We are the experts” in our own field of research, then why do we even do it in the first place? In business though, who is the expert is not something one fights for if the end product or contribution to profit is not made.

The current economic conditions caused many large biotech and pharma companies to lay off thousands upon thousands of employees, in one case of Pfizer layoff, scientist positions were particularly targeted for elimination. Life goes on. Economic downturns are also opportunities for becoming lean and mean, using ways of doing things with much improved efficiency and productivity such as outsourcing, and finding new areas for long term growth.
