Cystathionine Beta Synthase Antibody / CBS

Overview

Cystathionine Beta Synthase antibody supplied as a purified reagent for IF, WB, FACS, IHC-P in Human, Mouse samples. This product is a polyclonal (rabbit origin) antibody (host: Rabbit; isotype: Rabbit Ig) intended for research use only. The target is commonly annotated with nuclear, cytoplasmic localization context, which may inform staining patterns.

Key elements and design rationale

• Antibody identity: Polyclonal (rabbit origin); host Rabbit; isotype Rabbit Ig.
• Format and purification: format: Purified; purity: Antigen affinity purified.
• Species reactivity (reported): Human, Mouse.
• Applications (listed): IF, WB, FACS, IHC-P.
• Immunogen / epitope context: A portion of amino acids 104-133 from the human protein was used as the immunogen for the Cystathionine Beta Synthase antibody..
• Localization: Nuclear, cytoplasmic (annotation-level guidance; cell state and isoforms can shift patterns).

These attributes help you align the antibody with the biological question (target state, sample type, and readout) while keeping interpretation grounded in appropriate controls.

Biological background

Cystathionine Beta Synthase is the intended antigen for this primary antibody. Reported biological context includes: CBS acts as a homotetramer to catalyze the conversion of homocysteine to cystathionine, the first step in the transsulfuration pathway. This protein is allosterically activated by adenosyl-methionine and uses pyridoxal phosphate as a cofactor. Subcellular localization information (Nuclear, cytoplasmic) can be useful when interpreting IF/ICC patterns and selecting compartment-enriched lysates for WB.

Research relevance and current trends

• Spatial and single-cell approaches: imaging-based and cytometry workflows increasingly quantify heterogeneity and relocalization rather than only bulk abundance.
• Interaction-centric biology: IP-based enrichment and proteomics are widely used to define complexes, binding partners, and context-specific interactomes.

Common research applications

• Immunofluorescence (IF): visualize localization and co-localization patterns in cells or tissues.
• Western blot (WB): compare relative abundance/isoform patterns across conditions and sample types; band shifts may reflect processing or post-translational modification.
• FACS: commonly used to measure relative target levels or localization changes in the context of the experimental question.
• IHC-P: commonly used to measure relative target levels or localization changes in the context of the experimental question.

Across these readouts, differences in signal intensity, localization, or complex enrichment are typically interpreted alongside sample-matched controls and independent evidence to distinguish regulation from technical variation.

Notes for experimental interpretation

• Isoforms, cleavage products, or post-translational modifications can alter apparent molecular weight and subcellular distribution; interpret bands and staining patterns in the context of expected biology and sample preparation.
• Species differences and epitope conservation may affect binding; use matched positive controls and orthogonal evidence when comparing across organisms.
• Control concepts: include appropriate isotype and secondary-only controls (for imaging), and consider genetic perturbations (knockout/knockdown/overexpression) or independent antibodies targeting distinct epitopes to strengthen conclusions.

Epitope context is defined by the immunogen description; when available, align this with known domains, PTM sites, or family homology to anticipate potential cross-reactivity patterns. As a polyclonal antibody, recognition spans multiple epitopes, which can improve detection across conformations but may broaden background depending on sample context.
