antibodies-online now lists 96 Stereospecific Detection Technologies products. After the recently concluded agreement, antibodies-online now offers 96 SDT products globally. The “keystone” product is Poly-HRP, an improved homopolymer HRP label. According to the number of HRP units, HRP20, HRP40 and HRP80 are available. It is used for manufacturing ultrasensitive detection reagents for products such as ELISA, Western Blotting, and IHC. The Poly-HRP conjugates are used in the same way as the usual HRP conjugates, as for example in ELISA. Due to the numerous HRP molecules in contrast to the usual HRP alternatives, the signal is stronger. Furthermore, they are specialised in providing evidence of HRP activities in immunoassays (different TMB substrates and further immunoassay reagents). In order to make the product more accessible, heteropolymers (e.g. with Streptavidin) are also available.

For generations conventional monoclonal and polyclonal antibodies have been the canonical affinity proteomics reagents. These time-tested tools have proven their function and versatility in a host of applications, over and over again. However, the antibody has some well-known limitations.

Well established and understood challenges that are presented during production and application of monoclonal and polyclonal antibodies have prompted many innovative researchers to search for an alternate approach, and in recent years a deluge of Ig alternatives have flooded into the market, each with its own set of benefits and abilities.

While these products have not yet gathered the widespread acceptance and use that conventional immunoglobulins currently enjoy, they often possess properties that make them superior options for certain applications. Will any particular alternative be able to dethrone the antibody, and take its place as the "go-to proteomics tool" in the researcher's toolbox?

In our most recent resource article Antibody and immunoglobulin alternatives, antibodies-online's Stefan Pellenz skillfully examines the various options available to researchers searching for an alternative solution.

Independent Validation Badge

antibodies-online, the world’s largest proteomics reagent distributor, was recently cited in the Nature News Feature Blame it on the antibodies, written by Monya Baker. The article, which highlights many of the persistent issues that researchers face with regards to locating and procuring high-quality proteomics reagents, mentions the antibodies-online sponsored independent validation initiative during a discussion about various proactive industry measures designed to remediate quality control concerns.

Fluorescence is among the most captivating of all natural phenomena. It is also one of the most commonly utilized and versatile tools in life-science or biomedical researcher's toolbox, with visually stunning fluorescence micrographs dominating the cover of popular, highly-regarded peer-reviewed journals.

In modern life-science research, fluorescent probes are used to label all manner of molecules, cells, and tissues for a variety of applications including spectroscopy, fluorescence microscopy, FACS/Flow Cytometry, Western blotting and many others.

On May, 4th, 2015, Dr. Andreas Kessell, managing director and co-founder of antibodies-online, will give a lecture at a networking event for BioRiver. BioRiver is a leading network for Biotechnology and Life Sciences experts in the Rhineland bioregion. Alongside Professor Andreas Engelen, Director of Online-Marketing at GFIU GmbH, Dr. Kessell will discuss marketing to scientists and the development of successful, scientifically focused marketing campaigns in a digital world. The lecture will take place at Qiagen headquarters, and will be followed by presentation of the 2015 Ernst and Young Biotechnolgy Report.
