Social Media for the Consumer

Business has become an ever changing, dynamic landscape where the power and information no longer lies strictly in the hands of “the right people.” In less than a decade Facebook has managed to link nearly a billion people from tech savvy teens to curious senior citizens. Similarly, Twitter sees over 340 million tweets that reaches over 500 million active users per day. Social media is a wide reaching technology with infinite possibilities that has been synthesized and is fueled by people, not corporations.

In a recent Industry report, 93% of businesses reported using social media as a marketing tool with the benefits being increased exposure and customer interaction (Stelzner, 2011). What does this study mean to consumers? Businesses are coming to you and responding to your feedback. Social media gives you, the consumer; back the power and the opportunity to benefit from your loyalty. Most businesses, from restaurants to labs, offer weekly tips or discounts on their services to the customers who “follow” or “like” them. Here at Allele Biotech, we have begun offering special weekly promotions, information about our products and interesting biotech news to our customers who either “follow” us on Twitter or “like” us on Facebook. For the entire month of August we are offering 15% off just for a “like” or “follow.” If you are one of the billion users, it doesn’t take much more than a click for instant rewards.

We recognize that the reason we create this technology and improve is because of the consumers. Allele Biotech would like to thank you for your loyalty and encourage you to remain active within our social media to push us forward and to help us continuously strive for more. With the creation and exponential popularity of social media, the power and information as become available to the most important people, the consumers.

Picture Blog — Making mRNAs by In Vitro Transcription for Transgene Expression and R-iPSCs

R-iPS Cell FAQ 2:
What is the expected yield from the in vitro trancription (IVT) reactions?

Performed as described, you should recover around 40 ug RNA from each 40 uL IVT reaction.

R-iPS Cell FAQ 3:
How can the success of the RNA synthesis protocol be assessed?

Run 500 ng (5 uL) of the concentration-adjusted products on an E-gel to check for consistent product yield and relative product sizes, and to confirm the absence of secondary bands or smears.
mRNAs can be effectively produced through in vitro transcription

Record number of papers citing the GFP-Trap group products in 2011

The following are references in regards to GFP Trap published in the second half of 2011 (not a complete list); a high quality GFP-binding protein based on a single domain antibody derived from Camelids. It is characterized by a small barrel shaped structure (13 KDa, 2.5nm X 4.5 nm) and a very high stability (stable up to 70°C, functional within 2M NaCl or 0.5% SDS). With much greater stability, specificity, and affnity, GFP-Trap®, the recent addition to antibodies for immunoprecipitation, should make GFP the most suitable tag for immunoprecipitation assays.

Year-end message from Allele Biotech

The year 2011 has been an exciting and eventful year for many people. Throughout the year, we have been working diligently to bring the best research methods in many areas to our fellow researchers through innovation and entrepreneurship. Thanks in part to the government’s stimulus and grant support in 2011, we established several new product lines, including the Stealth iPS induction mRNA templates and reagents, a great new photoconvertible fluorescent protein in mClavGR2 (through collaboration with academic colleagues), and a highly efficient lentivirus-based shRNA packaging service as a result of an NCI SBIR contract.

As you all must have noticed by now, in July we redesigned our website to present our products in an easier, more user friendly manner, while adding a convenient online purchasing system. We have received a lot of positive feedback from customers telling us how “cool” the new site is, and how easy it is to use and redeem promotions. Towards the end of the year, our dedicated marketing and sales teams reinstated our biweekly email newsletters (to receive our messages on new discoveries and technologies, or be the first to use our promotions, sign up online under “Newsletter”).

All of these efforts would have been meaningless without our customers, who ultimately gave us the opportunity to be in the business we love and are trained to do. By selecting our products, sending us feedback, and “retweeting” or “reposting” our messages, you have been tremendously valuable to every one of us here at Allele. We thank you from the bottom of our hearts. In return, we will continue to invest and do our very best to provide new tools for advancing your research. Watch for our brand new monomeric fluorescent protein that can be nearly 10 times brighter than EGFP; a more powerful iPSC generation method that could potentially reprogram in just a few days, and much much more in 2012!

Making Recombinant Glycosylated Proteins (I)

Many mammalian cell membrane-bound and secreted proteins are glycosylated. The degree of their modifications may be dependent upon tissue specificity and cellular states such as normal vases cancerous. The existence of these proteins in bodily fluids, in combination to their relevance to diseases, makes glycosylated proteins good candidates for clinical diagnostics. Understanding the biogenesis, structure, and functions of these proteins will also aid research and prevention of cancers.

Cancer formation is a heterogeneous and complex process, involving many factors and cellular signaling pathways in each type of cancer. There are more than 1,200 potential cancer biomarkers identified in the literature by a 2006 review. We found that ~ 70% of the 1,261 proteins listed in are naturally secreted proteins, and some 40-50% glycosylated. The addition of carbohydrate groups during protein glycosylation to asparagines (N-linked), or threonines or serines (O-linked) residues may result in mono-, disaccharide- or branched oligosaccharide composed of as many as 20 monosaccharide residues. Glycosylation, together with other modifications, often change the apparent molecular mass of a secreted protein to many folds to that predicted by amino acid sequence. Such heavy modifications on the surface of proteins can influence their functions as well as characteristics as antigens or analytes. Studies of glycosylated proteins offer great opportunities for improving cancer diagnostics.

There are increasing demands for these glycosylated human proteins in good quantity, purity and affordability by the scientific community to perform fundamental and clinical studies in relation to cancer. Such proteins cannot be expressed in bacteria or yeast because those cells do not carry out equivalent post-translation modifications (PTM) as in mammalian cells. Although there have been successful attempts to modify yeast cells to produce proteins with certain types of glycans attached, they were designed for expressing a few pharmaceutical proteins and not suitable for expressing a wide variety of cancer markers. Aside from PTM, expressing human proteins in microorganisms may be hindered by their different codon usage preferences and protein folding tendencies.
