MTR Antibody / Methionine synthase

Overview

MTR Antibody / Methionine synthase is a research-use antibody directed against MTR. It is supplied for use in common immunoassay contexts such as WB, IHC-P, FACS, Direct ELISA (RUO).

Key elements and design rationale

• Target: MTR.
• Description (provided): Methionine synthase, also known as MS, MeSe, and MetH, is responsible for the regeneration of methionine from homocysteine.
• Antibody type: Rabbit, Polyclonal (rabbit origin), Rabbit IgG.
• Format: Antigen affinity purified; Affinity purified.
• Species reactivity: tested: Human, Mouse, Rat.
• Immunogen (if provided): A human recombinant protein (amino acids V880-D1095) was used as the immunogen for the MTR antibody..

The information above helps you match the antibody format to your assay context, interpret species-dependent differences, and anticipate how epitope context (isoforms, PTMs, or conformational state) may influence signal.

Biological background

Methionine synthase, also known as MS, MeSe, and MetH, is responsible for the regeneration of methionine from homocysteine. In humans it is encoded by the MTR gene (5-methyltetrahydrofolate-homocysteine methyltransferase). It is mapped to 1q43. This gene encodes the 5-methyltetrahydrofolate-homocysteine methyltransferase. This enzyme, also known as cobalamin-dependent methionine synthase, catalyzes the final step in methionine biosynthesis. Mutations in MTR have been identified as the underlying cause of methylcobalamin deficiency complementation group G. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

For curated annotations (gene/protein naming, domains, isoforms, and pathway links) for MTR, consult primary databases such as UniProt, NCBI Gene, and Ensembl.

Research relevance and current trends

• Context-dependent expression studies: researchers often examine MTR abundance and localization across perturbations (genetic, pharmacologic, or environmental) to connect phenotype to molecular changes.
• Reagent reproducibility: there is growing emphasis on antibody specificity checks using orthogonal approaches (e.g., genetic perturbation or independent antibodies) and transparent reporting of clone/lot information.
• Multi-modal datasets: antibody-based readouts are increasingly combined with transcriptomics and imaging to relate protein-level measurements to cell-state transitions.

Common research applications

• Western blotting (immunoblot) for relative detection of target protein abundance and apparent molecular weight.
• Immunohistochemistry for spatial mapping of target expression across tissues and cell types.
• FACS: commonly used to detect or compare MTR across experimental conditions (conceptual guidance only).
• Direct ELISA: commonly used to detect or compare MTR across experimental conditions (conceptual guidance only).

When comparing conditions, interpret changes in signal in the context of sample composition, expected localization, and any known isoform complexity for the target.

Notes for experimental interpretation

• Isoforms and PTMs: alternative splicing or post-translational modifications can change epitope accessibility and apparent molecular weight; interpret bands/signals accordingly.
• Cross-reactivity and matrix effects: background binding can vary by sample type, species, and blocking/detection chemistries; include appropriate negative controls.
• Control concepts: where feasible, use genetic perturbation (KO/KD/overexpression), orthogonal assays, or independent antibodies to support specificity claims.

Antibody considerations: Polyclonal reagents may recognize multiple epitopes and can increase sensitivity but may show broader binding profiles, while monoclonal clones provide a single-epitope readout that can improve consistency across experiments. If a conjugate is listed, the antibody supports more direct detection workflows; otherwise, it is typically used with a compatible secondary antibody.
