FR Antibodies

Santa Cruz Biotechnology supplies a comprehensive collection of FR Antibodies, specifically targeting the folate receptor (FR). FR Antibodies are suitable for western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). The folate receptor plays a critical role in cellular uptake of folate, which is essential for DNA synthesis and repair, making it vital for cell proliferation and survival. FR expression is often upregulated in certain cancers, highlighting its significance as a potential therapeutic target and biomarker in oncology research. Understanding folate receptor function and regulation can provide insights into tumor biology and treatment strategies. FR monoclonal antibodies enable precise detection and analysis of folate receptor expression patterns across various cell types and tissues. Investigating folate receptor mechanisms can lead to breakthroughs in cancer research and therapeutic development. Santa Cruz Biotechnology monoclonal antibodies for FR support researchers worldwide in advancing our understanding of cancer biology and potential treatment approaches.
