Get your antibody results validated in 5 weeks for $5000/€5000*

In the Sept 14th 2017 publication in Science, the challenges and pitfalls associated with the use of antibodies were highlighted. This is not a new revelation, as the problems surrounding the use and validation of antibodies have been discussed in the past (see articles bottom of the page). There are a limited number of commercial antibody manufacturers that develop and validate their own antibodies, with articles citing that these companies operate more like department stores.  As a consequence, the IHC user would buy from one company and have to perform their own independent validation, costing lots of money, time and samples, often resulting in questionable results. In absence of a quick and easy antibody validation method, orthogonal validation like RNAscope technology can provide an initial quick and easy way to validate antibody results.

Example of antibody validation with RNAscope ISH

Distribution of the c-MYC gene product in colorectal neoplasia  (Histopathology 2016), Baker et al. use RNAscope® Assay to detect MYC mRNA in clinically relevant samples, and thereby determine the reliability of MYC targeting antibodies.
The authors performed IHC on human FFPE normal colon (n = 15), hyperplastic polyps (n = 4) and neoplastic colon samples (n = 55) using the N-terminally directed antibody Y69, the C-terminal antibody 9E10, and compared with RNAscope® Assay in serial sections.
They found the localisation of MYC mRNA correlated well with the protein distribution determined by the N-terminally directed antibody Y69 while the 'gold standard' antibody 9E10 often showed a reciprocal pattern of expression.  
They conclude that "the observed discrepancy between the staining patterns suggests that the significance of 9E10 in immunohistochemical staining is currently uncertain, and therefore should be interpreted with caution

Why use RNAscope® technology to orthogonally validate your IHC antibody results?
  • Easy single-day RNAscope Assay provides rapid validation.

  • RNAscope® Assay is sensitive, specific, reliable and cited in nearly 1000 publications.

  • Designed for virtually any target, in any species.

  • Enables a quick comparison of RNA and protein expression (using IHC antibodies). 

  • RNA-based detection, RNAscope assay is truly an orthogonal method that both validates and can provide additional insights for gene expression.

  • Widely used by industry; protocols available

Why use Pharma Assay Services (PAS)?
  • Expert team with over five years of experience in RNAscope® ISH  

  • Each project is individually tailored and managed by our team of scientists, specialists, board-certified pathologists, and data experts.

  • Get your RNAscope results in 5 to 6 weeks for only $/€5000!
