This panel contains 4 recombinant rabbit monoclonal antibodies that are all knock-out validated to ensure specificity to their targets. They are provided as a sampler panel to allow you to easily evaluate each in your required application.\u003cbr\u003e\nDNA mismatch repair (MMR) proteins are involved in repairing mistakes that occur during DNA replication and recombination, in addition to repairing some types of DNA damage. Defects in the MMR process due to mutations in MMR genes (MSH6, PMS2, MLH1, MSH2) can result in microsatellite instability (MSI), where a DNA sequence accumulates errors and produces abnormally long or shorter microsatellites. These defects in the MMR pathway have been linked to various human cancers, such as human non-polyposis colon cancer (HNPCC) and Muir-Torre Syndrome (MTS), a subtype of HNPCC.\u003cbr\u003e\nFor guidelines on how to use each antibody within the panel, please consult the individual datasheet for each antibody.\u003cbr\u003e\nPanel contains:\u003cbr\u003e\n- Rabbit monoclonal [EPR3894] to MLH1 (20 μL)\u003cbr\u003e\nab92312\u003cbr\u003e\n- Rabbit monoclonal [EPR21017-123] to MSH2 (20 μL)\u003cbr\u003e\nab227941\u003cbr\u003e\n- Rabbit monoclonal [EPR3945] to MSH6 (20 μL)\u003cbr\u003e\nab92471\u003cbr\u003e\n- Rabbit monoclonal [EPR3947] to PMS2 (20 μL)\u003cbr\u003e\nab110638\u003cbr\u003e\nExplore our range of antibody sample panels designed to provide you with a variety of trial-size antibodies in a convenient and cost-effective format.\u003cbr\u003e\nCarrier-free formulations of our recombinant antibodies are also available for easy conjugation to labels of your choice and for multiplex applications.

MSH2 also known as MutS Homolog 2 has a molecular mass of approximately 100 kDa and commonly pairs with MSH6 to form a complex. These proteins are expressed in various tissues and are critical components for recognizing and repairing mismatches during DNA replication. These components are essential for maintaining genomic stability and preventing mutations from accumulating.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nMSH2 and related proteins assemble into essential heterodimeric complexes for the mismatch repair system. MSH2 pairs with MSH6 to form the MutSα complex while MLH1 partners with PMS2 to create the MutLα complex. Together these complexes identify and initiate repair of DNA base mismatches that can arise during replication. This precise operation ensures that the DNA's faithful transmission occurs from one generation of cells to the next highlighting the importance of maintaining integrity in diseases where genome instability is a factor.\u003cbr\u003e\nPathways\u003cbr\u003e\nThese mismatch repair proteins are pivotal in the cell cycle control and DNA damage response pathways. The MMR pathway is closely associated with the p53 pathway which detects damage and can promote apoptosis if the mutation burden is high. MSH2 plays an important role in recognizing mutation-inducing errors and it directly interacts with other proteins like MLH1 to maintain this checkpoint. These pathways collectively guard the cell against tumorigenesis by facilitating accurate DNA repair or triggering cell death in the face of irreparable damage.\u003cbr\u003e\nDefects in mismatch repair proteins including MSH2 correlate strongly with Lynch syndrome also known as hereditary nonpolyposis colorectal cancer (HNPCC). This condition arises due to inherited mutations that impair the MMR system. In this context MSH2 mutations frequently co-occur with MLH1 mutations significantly elevating the risk of colorectal and endometrial cancers. Determining the status of MMR proteins using immunohistochemistry (IHC) such as the MMR IHC panel assists in diagnosing these disorders and guiding therapeutic decisions.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46847584567465,"sku":"ab252190","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab252190","provider":"Iright","version":"1.0","type":"link"}
