How We Give Back in 2010
This year has started off great for Allele. Every week our shipping volume is increasing, we have an arsenal of new products in the pipeline, we are the sole provider of oligos on the University of California San Diego’s central online purchasing site, and every day we are taking even more action to cut the waste and increase productivity in order to give our customers the very best at a reasonable cost. Our company is maturing nicely in its 10th year!
Lately we have really been focusing on giving back to our customers who I, on a daily basis, am impressed with. Most of all, I am impressed with how good of a relationship we have. I have several customers who I am on the phone with regularly and genuinely glad to hear from. We have fun with our friends on facebook, giving advice on molecular biology techniques and even swapping recipes.
So far this year we have designed three new ways to reward our customers:
There is our big 10 Year Anniversay Oligo Giveaway where we will give away a free month of oligos to one facebook friend or fan. DNA and RNA oligos were Allele’s very first product and we knew we wanted to have a big prize to reward to celebrate not only 10 years in business but also surviving through what is the worst economic time in decades. It only made sense that the giveaway should be oligos. Most importantly, this is also where our longest customer relationships exist; within our oligo customer base. Personally, I cannot wait for the winner to be announced. I am probably more excited about it than most of the contestants!
This last January we also launched our Allele Biotech Rewards Program designed by our Business Development Manager Eugene Pahk. We want to make it more affordable for all Allele customers to purchase Allele Biotech Products (we have over 1000). Allele Rewards are easy to earn and more importantly, easy to redeem. We do not make it complicated, rewards do not expire, and they can be used on a number of common molecular biology research tools. Just another way to give back to the people who keep us in business and support our research.
Our latest tribute to our patrons is especially designed for all the younger, tech savvy (and usually desperately in need of money) grad students! We will award $100 cash to anyone who submits an Allele product or service relevant picture to us for use on our homepage. We are tired of the current photos we have now and instead of just purchasing some (which we could do for a really low cost) we decided to get the force of our creative and intelligent supporters to not only have some fun but to get a different perspective on what the Allele brand means to people.
On top of the new programs and promotions, every week we make a promise to have one item or service on sale; sometimes at the direct behest of the researchers themselves. Our weekly promotions are announced via our social networking sites (facebook, twitter, Linkedin, myspace, and our Allele Biotech Blog). We want to have as many avenues as possible for customers to be involved with Allele Biotech so we can succeed in this business for decades to come while giving back to our customers the entire way.
Become a friend, fan, follower, contact, or bookmark our blog site today to get the most of what we give!
Monitoring the Undifferentiated Stage of Stem Cells—the Pluripotency Markers
Human embryonic stem (ES) cells or induced pluripotent stem (iPS) cells promise to serve as an unlimited source for transplantation or tissue-specific differentiation. However, obtaining and maintaining stem cells are very difficult tasks for multiple reasons. For instance, most stem cell lines tend to spontaneously differentiate in culture, and even if the cells form stem cell-like colonies, they may be of a heterogeneous population.
To identify pluripotency of stem cells, expression of stem cell-specific marker genes (i.e. Oct-3/4, Sox2, Nanog, Rex-1) is monitored by RT-PCR. Alkaline phosphatase activity and methylation profiles of promoters of pluripotency-relevant genes are often analyzed as well. Compared to murine cells, it is noticeably more difficult to obtain human iPSCs, of which stem cell-like colonies sometimes turn out not to be pluripotent cells. We highly recommend testing iPSCs, especially human iPSCs, with antibodies against stage-specific embryonic antigens such as SSEA-3, SSEA-4, TRA-1-60, and TRA-1-81.
However, all of these methods require cell destruction or fixation for analysis, therefore, are inconvenient and costly. Furthermore, many studies using ES or iPS cells involve differentiation of stem cells into different lineages, a method for observing live cells to know their undifferentiation/differentiation stages would be very helpful. There have been a number of publications using murine Oct-4, Nanog, and Rex-1 promoter driven fluorescent proteins as markers for pluripotency tests [1-3]. Allele Biotech provides, under its iPS product line, packaged and validated lentiviral particles that would insert these 3 promoter-FP reporters into the stem cells. Although currently these promoters are of mouse sequences, their use in human stem cells have been reported.
