Why use RNAscope® ISH as an alternative method to IHC?
1. Data quality
"We were very excited that RNAscope® worked as we had had a horrible struggle with bad antibodies -We actually tested 13 different antibodies with different conditions and didn't get trustworthy results- so the RNAscope assay saved us”
Emmi Rotgers, Institute of Biomedicine/Physiology, Turku, Finland
- " even though we observed a significant correlation between PDL1 mRNA expression as detected by RNAscope in situ hybridization and PD-L1 protein expression as detected by IHC using two different antibodies, the signal to noise ration of RNAscope® probe was far better that observed with IHC detection."

- "the COL11A1 protein levels and pattern of expression in the serial sections were consistent with COL11A1 RNA levels and pattern of expression; however, in situ hybridization provided a higher resolution signal at a cellular level."
A collagen-remodeling gene signature regulated by TGF-β signaling is associated withmetastasis and poor survival in serous ovarian cancer. Cheon DJ, Tong Y, Sim MS, Dering J, Berel D, Cui X, Lester J, Beach JA, Tighiouart M, Walts AE, Karlan BY, Orsulic S.Clin Cancer Res. 2014 Feb 1;20(3):711-23.
With just 3 weeks from sequence submission to probe delivery in your lab and reliable and reproducible performance guaranteed on positive target samples, RNAscope® ISH becomes a very attractive option, particularly when the true costs of rigorous antibody developement and validation standards are given full consideration. Why wait for an antibody to be developed and validated, get started now with RNAscope® ISH to accelerate your research.
3. Any Target
ACD proprietary probe design algorithm allows to probe design for any gene with an unique sequence of 300 base pairs in any species including engineered animal models like knockout mouse model, xenograft models, transgenic models or humanized mouse. Researchers are no longer limited to interrogating just targets with available antibodies, they routinely apply RNAscope ISH to targets with no antibodies or poor-quality antibodies.
