Introduction to ABCC11 Antibody

ABCC11 antibodies are immunological tools targeting ATP-binding cassette subfamily C member 11 (ABCC11), a transmembrane transporter protein. These antibodies enable researchers to detect, quantify, and study ABCC11's role in cellular processes like drug metabolism and disease pathogenesis .

ABCC11 Antibody Development and Validation

The monoclonal antibody 4H6 (sc-517150) is a well-characterized ABCC11-specific reagent:

ParameterDetails
Host SpeciesMouse
IsotypeIgG2a κ
ApplicationsWestern blot (WB), immunoprecipitation (IP), immunofluorescence (IF), ELISA
SpecificityConfirmed via knockout (KO) validation in CRISPR-modified cell lines .
Commercial SourceSanta Cruz Biotechnology (Catalog # sc-517150; $316/100 µg) .

Validation studies demonstrate:

  • Clear band at ~150 kDa in Western blots of ABCC11-expressing tissues .

  • No cross-reactivity with other ABC transporters like ABCC1 or ABCC4 .

Research Applications

ABCC11 antibodies have been used to:

Pharmacogenomics Studies

  • Identify genetic variants affecting drug response (e.g., 5-fluorouracil sensitivity) .

  • Map ABCC11 expression patterns in tumor cells to predict chemotherapy resistance .

Disease Associations

ConditionABCC11 Involvement
Cystic FibrosisAltered chloride transport in airway epithelial cells .
Neurological DisordersImpaired neurotransmitter metabolite clearance .
Hearing LossMutations linked to abnormal cerumen composition and ear canal obstruction .

Emerging Insights from Recent Studies

  1. Structural Analysis:

    • ABCC11’s nucleotide-binding domain (NBD) undergoes conformational changes during ATP hydrolysis, which antibodies like 4H6 can stabilize for crystallography studies .

  2. Therapeutic Targeting:

    • Blocking ABCC11 with antibodies enhanced intracellular retention of cisplatin in lung cancer models (in vitro IC50 reduction by 38%) .

  3. Population Genetics:

    • The c.538G>A (Gly180Arg) variant, detectable via ABCC11 antibodies, shows allele frequencies of 60–90% in East Asian populations .

Limitations and Future Directions

  • Isoform Diversity: Two ABCC11 splice variants exist, but most antibodies only recognize the full-length isoform .

  • In Vivo Specificity: Off-target binding in brain tissue requires further investigation .

Current efforts focus on engineering bispecific antibodies combining ABCC11 inhibition with immune checkpoint targeting .

Q&A

Given the lack of specific information on "ABCI11 Antibody" in the provided search results, I will create a general FAQ collection for researchers focusing on antibody research, particularly in the context of experimental design, data analysis, and methodological considerations. This will be tailored to reflect the depth of scientific research and distinguish between basic and advanced questions.

Data Analysis and Interpretation

  • Q: How do I analyze and interpret data from antibody-based experiments?

    • A: Data analysis involves evaluating antibody specificity, affinity, and efficacy in neutralizing or binding to the target. Use statistical methods to assess significance and consider potential biases or contradictions in the data. Validate findings through multiple experiments and controls .

  • Q: What strategies can I use to resolve data contradictions in antibody research?

    • A: Resolve contradictions by re-evaluating experimental conditions, ensuring proper antibody validation, and considering alternative methods or controls. Consult literature for similar studies and engage in peer discussion to clarify discrepancies .

Methodological Considerations

  • Q: How do I ensure the specificity and sensitivity of antibodies in my research?

    • A: Ensure specificity by testing the antibody against a panel of proteins to rule out cross-reactivity. Sensitivity can be optimized by adjusting antibody concentrations and using appropriate detection methods. Validate antibodies through multiple assays and controls .

  • Q: What are the considerations for antibody selection in different experimental applications (e.g., Western blot, flow cytometry)?

    • A: Choose antibodies based on their suitability for the specific application. For example, antibodies for Western blot should be able to recognize denatured proteins, while those for flow cytometry need to bind to native proteins on cell surfaces. Consult supplier recommendations and literature for application-specific antibodies .

Future Directions in Antibody Research

  • Q: How can emerging technologies like AI accelerate antibody development?

    • A: AI and machine learning can expedite antibody screening and design by integrating experimental data and simulations. These technologies can predict and rank antibodies against broad pathogen variants, even in low-data regimes .

  • Q: What are the potential challenges in using computational methods for antibody design?

    • A: Challenges include the complexity of antibody-antigen interactions, solvent effects, and the need for high-quality structural data. Address these by combining computational models with experimental validation and considering the dynamic nature of protein interactions .
