Overview
Anti-CART Antibody is an antibody targeting Cocaine-And Amphetamine-Regulated Transcript Protein, CARTPT, CART Prepropeptide Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IHC, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Cocaine-And Amphetamine-Regulated Transcript Protein, CARTPT, CART Prepropeptide (also reported as Cocaine-And Amphetamine-Regulated Transcript Protein, CARTPT, CART Prepropeptide).
- Immunogen/epitope region: Secreted.
- Homology note: Mouse, rat, human - 13 out of 14 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Specificity statement (as provided): The antibody will recognize the precursor (proCART) and both active CART peptides: CART (55-102) and CART (62-102). The human counterpart called CART (42-89) is identical to CART (55-102)..
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
CART peptide, known by the name CARTPT - Cocaine-And Amphetamine-Regulated Transcript Protein. CART peptide is a satiety factor closely associated with the actions of leptin and neuropeptide Y. This anorectic peptide inhibits both normal and starvation-induced feeding and completely blocks the feeding response induced by neuropeptide Y (NPY) and regulated by leptin in the hypothalamus.
Research relevance and current trends
- Comparing target expression across perturbations, genotypes, or treatment conditions.
- Interpreting localization shifts alongside pathway or phenotypic readouts.
- Using orthogonal controls (KO/KD, peptide competition, isotype concepts) to support conclusions.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-NT047.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
