vPair^TM antibodies, developed at Abiocode using a proprietary premier antibody-production technology, represent a pair of fully characterized antibodies that recognize two different regions of a target protein. vPair^TM antibodies bring value and validation in antibody-based research.

When studying a protein employing antibodies, we often face the issue as whether the signal observed truly represents the protein of interest. For example, the sizes of proteins observed on Western blot often different from calculated molecular weights due to many factors such as posttranslational modifications. Although gene knockout or knockdown can allow the validation of signal specificity, these technologies are often not available or applicable for many applications such as the analysis of tumor samples by IHC. The use of a pair of fully characterized vPair^TM antibodies in the same study can validate signal specificity since vPair^TM antibodies recognize two independent epitopes of the same protein. At Abiocode, we are committed to develop vPair^TM antibodies that can work in various applications, including antibody arrays, Western blot, IP-Western, ChIP, IHC, FACS, etc.
