This aspiration became one of our earliest targets at Proteintech; to produce high quality
antibodies for every known human protein by the year 2015. From the first antibodies
made to the 11,000 and counting in our inventory today, we make every single one with the
knowledge and expertise of our Proteintech scientists. Our company and mission have grown on the foundations of these high-standard antibodies.
At Proteintech we appreciate that you need antibodies you can trust. Being able to trace
every step of an antibody’s production gives you a significant advantage, even before you
use it in your work; it helps to know how your antibody has been made and to what
extent it has been validated. Proteintech Group can provide this information as we make
every single one of the antibodies we sell, giving us complete control over their quality and
validation. For example, you can access any validation data instantly due to our systematic
validation procedures and records. This information is available in our datasheets and
through our P-View database on our website.
Our validation process is one you can really trust as we use primary tissues and regular
cell lysates to perform all of our validation western blots. If our antibodies do not make
the grade, we develop them again from the very beginning. You can be sure that any
Proteintech antibody you choose will be successful when they make the transition from our
validation to your experiments. We are so confident of this we have covered them with a
100% money back guarantee to give you 100% peace of mind.
Major Histocompatability Complex (MHC) II, found on antigen presenting cells, is an
integral part of the antibody production process. MHCII molecules select and present
the host immune system with antigen and have been optimized for this process by nature
over millions of years. They naturally select the best epitopes for an immune response,
preferring whole protein antigens over peptides. This ultimately produces antibodies that
recognize the natural conformation of the target protein, allowing higher binding affinity in
all circumstances i.e. in intact or partial protein samples.
Proteintech antibodies have been designed and raised against the whole recombinant protein,
rather than a single peptide antigen. This gives our antibodies superior protein recognition
capabilities and versatility, meaning you can use them in any application. In many assays,
epitopes are destroyed or hidden; for example, the cross-linking process of IHC severely
compromises protein structure. In these situations, antibodies raised against a peptide will
normally lose their effectiveness as they recognize only one epitope – there is a higher chance
of losing the recognition site for that antibody entirely. Whole protein antigen-generated
antibodies however, are a mixture of many IgGs specific for the target protein, so even if
many epitopes are lost there is a much higher probability of successful binding.
All of us at Proteintech appreciate that you want to know your antibody better before
you invest valuable time in its use. We have a wealth of validation information about these
antibodies instantly available in our interactive P-VIEW (protein expression via IHC, ELISA
and WB) database on our website. This means you have on-demand access to all of our
original data, anytime, anywhere. Furthermore, everyone can add any extra validation data
they find with our antibodies, making P-VIEW a truly interactive and universal reference
database. All this enables you to discover the science behind every one of our antibodies,
whenever or wherever you need to, be it lab, classroom or conference.
All of us at Proteintech value you the scientist. We go to great lengths to ensure that
you are happy with every antibody you buy and your experience with us. From the first
moment you browse our website to publication success and beyond, we provide the
highest standard of customer service.
Round the clock support for any questions you may have we are instantly available
via our Live Chat service. We have offices covering all time zones so you will always be
connected to a Proteintech representative when you need to be.
Next day delivery when you choose an antibody, we ship it immediately meaning you
receive your antibody the next day; we can achieve this because we maintain a worldwide
inventory of our antibodies, made easy because we are the original manufacturer.
For all of your publications featuring any of our antibodies we will reward you with an
antibody of your choice. We commit to this because we see every customer as our
collaborator in research; your success is our success.
At Proteintech, we take a wholehearted interest in the scientific discoveries our antibodies
have contributed to and actively produce news articles and media showcasing them.
We would love to hear about your scientific success and any thoughts you have on our
products; we appreciate any feedback we receive. If you have something to share with us
