Product Details
Background
Mismatch repair (MMR) proteins is a group of nuclear enzymes, which in all proliferating cells participate in repair of base-base mismatch, that occur during DNA replication. Loss of MMR proteins leads to an accumulation of DNA replication errors in the proliferating cells, particularly in areas of the genome with short repetitive nucleotide sequences, a phenomenon known as microsatellite instability (MSI).The PMS2 protein forms a heterodimer with the MLH1 protein which is then activated in the presence of ATP; this complex coordinates the binding of other proteins that repair DNA errors arising during cell preparation for cell division. The loss of PMS2 expression in tumors can be helpful in identifying hMLH1 mutation carriers and identifies their suitability for mutation analysis. PMS2 gene defects account for a small but significant proportion of colorectal cancers and for a substantial proportion of tumors with microsatellite instability.Compared to molecular biological techniques, immunohistochemical analysis of MMR protein expression is much simpler and cheaper. Immunohistochemical analysis helps to pinpoint the affected gene and should be readily accessible in a pathology laboratory.
Application
To ensure optimal assay performance, AREX recommends conducting reagent titration tailored to each testing system for optimal detection results.
*Results are sample-specific. Please refer to your local assay conditions and test parameters for reference.

FAQs
Are the pathology antibodies provided by AREX raw antibodies or ready-to-use solutions?
AREX Biosciences specializes in supplying high-quality IHC pathology raw antibodies (Raw Antibodies). We do not manufacture ready-to-use working solutions or IVD diagnostic reagents. We mainly provide concentrated raw materials to pathology reagent manufacturers and diagnostic platform companies to support product development and OEM production.
What development scenarios are pathology raw antibodies mainly used for?
Our raw antibodies are primarily used for the research, performance optimization, validation, and commercial-scale production of pathology IHC detection reagents. They are also suitable for companion diagnostics (CDx) projects and antibody screening.
How can I evaluate whether a raw antibody is suitable for our staining platform?
It is recommended to focus on specificity, sensitivity, background control, and performance on your target automated platforms (such as Roche Ventana, Leica Bond, Agilent Dako, etc.). We can provide internal test data for reference, but we recommend partners perform actual validation on their own platforms.
Can you provide samples for platform validation?
Yes. We can provide validation samples depending on the specific product. Some products may be provided free of charge, while others may involve a small sample fee. Handling fee and shipping fee will be charged separately. Please contact us for detailed confirmation.
How should raw antibodies be paired with detection systems?
AREX raw antibodies can be used with various polymer detection systems and ancillary reagents. We recommend optimization in combination with the ARExVisual® system or your existing detection platform to achieve better signal intensity and background control.
