Introduction to ABCB1 Antibodies

ABCB1 antibodies are specialized immunoglobulins designed to detect and quantify the ABCB1 protein (also known as P-glycoprotein or MDR1). ABCB1 is a 170 kDa transmembrane glycoprotein encoded by the ABCB1 gene, functioning as an ATP-dependent efflux pump that exports xenobiotics, chemotherapeutic agents, and other substrates out of cells . Antibodies targeting ABCB1 are pivotal tools for studying drug resistance mechanisms in cancer, pharmacokinetics, and blood-brain barrier function .

Key Applications of ABCB1 Antibodies

ABCB1 antibodies are utilized in:

  • Western blotting: Detecting endogenous ABCB1 protein levels in cell lysates (e.g., Cell Signaling Technology #12273 and #13978) .

  • Immunohistochemistry (IHC): Localizing ABCB1 in tissue sections for clinical diagnostics .

  • Flow cytometry: Quantifying ABCB1 expression on cell surfaces .

  • Functional studies: Investigating ABCB1's role in multidrug resistance (MDR) and its inhibition .

Critical Research Insights:

  • Drug Resistance: ABCB1 overexpression in cancer cells (e.g., MCF7/ADR, SW620/Ad300) reduces intracellular accumulation of chemotherapeutics like doxorubicin and FN-1501 . Inhibition using agents like VPM (ABCB1 inhibitor) restores drug sensitivity .

  • Genetic Variants: SNPs (e.g., c.1199G>A) and transcriptional fusions alter ABCB1 function, impacting drug efficacy .

  • Clinical Relevance: ABCB1 inhibitors (e.g., PSC833) enhance cytotoxicity of substrates in lung cancer models .

  • Flow Cytometry: HEK293 cells transfected with ABCB1 show 92.6–98.6% surface positivity, confirmed via QIFIKIT assays .

  • ATPase Activity: ABCB1 ATPase stimulation by FN-1501 (Kd = -9.77 kcal/mol) indicates strong substrate binding .

Clinical Implications

ABCB1 antibodies are critical for:

  • Identifying patients with ABCB1-driven drug resistance in AML and solid tumors .

  • Developing antibody-drug conjugates (ADCs) to bypass ABCB1-mediated efflux .

  • Personalizing therapies using ABCB1 inhibitors (e.g., zosuquidar) to enhance chemotherapeutic efficacy .
