Overview
Anti-Neurotrophin 3 (NT-3) Antibody is an antibody targeting NTF3, Nerve growth factor 2, NGF2, HDNF Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IF, IHC, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: NTF3, Nerve growth factor 2, NGF2, HDNF (also reported as NTF3, Nerve growth factor 2, NGF2, HDNF).
- Immunogen/epitope region: Intracellular.
- Homology note: Rat, mouse, chicken, Xenopus - identical; cat - 9/10 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Cited use: IP, IHC (literature use does not guarantee performance in every setup).
- 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
The neurotrophins ("neuro" meaning nerve and "trophe" meaning nutrient) are a family of soluble, basic growth factors which regulate neuronal development, maintenance, survival and death in the CNS and PNS.1 The structural hallmark of all neurotrophins is the characteristic arrangement of the disulfide bridges, known as the cysteine knot, which has been found in other growth factors such as PDGF.2 The rat and human forms of neurotrophin-3 (NT-3) are 96% homologous. NT-3 has been shown to strengthen synaptic connections to motoneurons in the neonatal rat,3 to serve as an anti-inflammatory factor, to suppress microglial activation,4 to play a critical role in regulating T helper 1/T helper 2 cell balance5 and to modify potassium currents in isolated inner hair cells from guinea pig cochlea.6 The biological effects of NT-3 are mediated by two receptors: TrkC, which is specific for NT-3, and p75NTR, which binds all the neurotrophins.7
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.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
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-NT003.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
