Id Antibodies

Santa Cruz Biotechnology supplies a comprehensive collection of Id Antibodies for advanced research in cellular and molecular biology. Id Antibodies are compatible with multiple techniques, including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). Id1, Id2, Id3, and Id4 proteins play crucial roles in regulating cell differentiation, proliferation, and survival. Id proteins function as dominant negative regulators of basic helix-loop-helix (bHLH) transcription factors, thereby influencing the development of various tissues and the immune response. Understanding the expression and function of Id1, Id2, Id3, and Id4 is essential for elucidating their involvement in cancer progression and other diseases. Researchers worldwide rely on Id1, Id2, Id3, and Id4 monoclonal antibodies to explore cellular pathways and molecular mechanisms. Current investigations focus on how Id proteins influence stem cell maintenance, cellular senescence, and tissue regeneration. Ongoing studies examine the relationship between Id protein expression and various pathological conditions. Santa Cruz Biotechnology monoclonal antibodies for Id proteins continue to advance scientific understanding of cellular development and disease mechanisms.
