CRYAB Antibody

Overview

CRYAB Antibody is a research-use primary antibody intended for detection of CRYAB in experimental workflows. It is supplied in Purified format. Key antibody attributes include Mouse, Monoclonal (mouse origin), clone CPTC-CRYAB-1, isotype Mouse IgG2c, kappa. Applications listed for this product include WB, IHC-P. Reported/annotated localization context: Cytoplasmic, nuclear. Species reactivity (as provided): Human, Rat.

Key elements and design rationale

• Target: CRYAB — selectivity and interpretation should be considered in the context of isoforms, post-translational modifications, and related family members when applicable.
• Format: Purified — format can influence background, multiplexing compatibility, and downstream detection strategies.
• Antibody identity: Mouse, Monoclonal (mouse origin), clone CPTC-CRYAB-1, isotype Mouse IgG2c, kappa — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
• Localization: Cytoplasmic, nuclear — expected subcellular distribution can guide band/structure interpretation and help flag off-target signal.
• Product notes (from provided description): Crystallins are the major proteins of the vertebrate eye lens, where they maintain the transparency and refractive index of the lens. Crystallins are divided into alpha, beta and gamma families, and the beta- and gamma-crystallins also compose a superfamily. Crystallins usually contain seven distinct protein regions, including four homologous motifs, a connecting peptide, and N- and C-terminal extensions. Alpha-crystallins consist of three gene products, alpha-A-, alpha-B- and alpha-C-crystallin, which are members of the small heat shock protein family (HSP 20). Alpha-crystallins act as molecular chaperones by holding denatured proteins in large soluble aggregates. However, unlike other molecular chaperones, alpha-crystallins do not renature these proteins. Expression of alpha-A-crystallin is restricted to the lens and defects of this gene cause the development of autosomal dominant congenital cataracts (ADCC). The human alpha-B-crystallin gene product is expressed in many tissues, including lens, heart and skeletal muscle. Elevated expression of alpha-B-crystallin is associated with many neurological diseases, and a missense mutation in this gene has co-segregated in a family with a Desmin-related myopathy.

Where multiple assay formats are possible, align the antibody format, host/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.

Biological background

In this catalog, CRYAB is positioned within Molecular & Cellular Biology research contexts. Localization annotations (e.g., Cytoplasmic, nuclear) can help contextualize expected signal patterns in imaging and fractionation-based readouts. For authoritative gene/protein nomenclature, domains/isoforms, and curated functional annotations, consult resources such as UniProt, NCBI Gene, and Ensembl.

Research relevance and current trends

• Higher-plex and spatially resolved readouts (e.g., multiplex IF/IHC, spatial omics) are increasing demand for well-characterized primary antibodies with clearly stated host/isotype and labeling strategies.
• Genetic perturbation controls (knockout/knockdown) and orthogonal measurements (e.g., RNA vs protein) are commonly used to strengthen target attribution when interpreting antibody-derived signals.
• Reproducibility initiatives emphasize transparent reporting of antibody identity (clone, host, isotype) and experimental context to improve cross-study comparability.

Common research applications

• WB: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• IHC-P: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• Typical workflow themes: Western blot validation, IHC on FFPE tissue, ELISA binding assay, Specificity controls.
• Workflow notes: Validate CRYAB by Western blot in cell/tissue lysates (include controls), Detect CRYAB by IHC in FFPE tissue sections (optimize antigen retrieval + dilution), Measure binding to CRYAB peptide/protein by ELISA with dil…

When comparing conditions, consistent sample processing and appropriate negative/positive controls support interpretation of qualitative localization differences and quantitative abundance changes.

Notes for experimental interpretation

• Isoforms and post-translational modifications may shift apparent molecular weight or epitope accessibility, especially across cell states or treatments.
• Species and tissue context can affect sequence conservation, expression level, and background binding; predicted reactivity should be verified in your sample.
• Control concepts include isotype-matched controls, secondary-only controls (for indirect detection), and genetic/orthogonal controls (e.g., KO/KD, independent antibodies, or RNA measurements) when feasible.

Monoclonal and polyclonal antibodies can differ in epitope recognition breadth and lot-to-lot characteristics; consider clonality and clone information (when provided) alongside your assay requirements. Conjugated formats may simplify detection but can change background and multiplexing behavior compared with unconjugated primaries.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
