Quantitate Human CFHR4 with 7.209 pg\/ml sensitivity.\u003cbr\u003e\nSimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits: Single-wash protocol reduces assay time to 90 minutes or less         -High sensitivity, specificity and reproducibility from superior antibodies         -Fully validated in biological samples         -96-wells plate breakable into 12 x 8 wells strips A 384-well SimpleStep ELISA® microplate (\u003cbr\u003e\nab203359\u003cbr\u003e\n) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nCFHR4 also known as Complement Factor H-Related 4 is a protein involved in the regulation of the complement system which plays an essential role in innate immunity. CFHR4 has a mass of approximately 86 kDa. The protein is part of the complement factor H protein family and expresses primarily in the liver and plasma. The protein features several short consensus repeat (SCR) domains that facilitate its interaction within the complement pathway therefore influencing immune system activity.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nCFHR4 modulates the activity of the complement system by binding to C3b a central component in complement activation. It is not a direct inhibitor but competes with Complement Factor H (CFH) for binding sites influencing factor H-mediated regulation. This positioning helps maintain a balance in complement activation and inhibition possibly preventing overactivation which could damage host tissues. CFHR4 does not form large complexes but operates closely with other complement regulators like CFH.\u003cbr\u003e\nPathways\u003cbr\u003e\nCFHR4 participates in the alternative complement pathway. The alternative pathway acts as a continuous surveillance system that does not require antibody-antigen interactions for activation. CFHR4 interacts with complement components such as C3b and CFH within this pathway contributing to the control and fine-tuning of complement activity under normal physiological conditions. CFH and CFHR4 both play a role ensuring that the complement system responds accurately to threats without damaging host cells.\u003cbr\u003e\nCFHR4 has implications in diseases like age-related macular degeneration (AMD) and atypical hemolytic uremic syndrome (aHUS). Variants or dysregulation of CFHR4 may disrupt complement control leading to inflammation and tissue damage associated with these conditions. The relationship between CFHR4 CFH and other complement components like C3b reveals the importance of balanced complement control in preventing these diseases. Understanding CFHR4's role assists researchers and clinicians in developing therapeutic strategies for conditions related to complement dysregulation.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843634581673,"sku":"ab314845","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab314845","provider":"Iright","version":"1.0","type":"link"}
