Overview
CD74 Antibody is an antibody targeting CD74, raised in Rabbit for protein detection and localization studies where these specifications are required.
Key elements and design rationale
- Target: CD74 (reported localization: Cell surface and paranuclear globular).
- Antibody identity: Polyclonal (rabbit origin); Rabbit IgG.
- Conjugate/label: Unconjugated (affects detection chemistry and multiplex compatibility).
- Format: Antigen affinity purified.
- Species reactivity: Human.
- Listed applications: WB, IHC-P, IF, FACS, Direct ELISA (refer to on-page specifications for application-specific guidance).
Biological background
HLA class II histocompatibility antigen gamma chain also known as HLA-DR antigens-associated invariant chain or CD74 (Cluster of Differentiation 74), is a protein that in humans is encoded by the CD74 gene. The protein encoded by this gene associates with class II major histocompatibility complex (MHC) and is an important chaperone that regulates antigen presentation for immune response. It also serves as cell surface receptor for the cytokine macrophage migration inhibitory factor (MIF) which, when bound to the encoded protein, initiates survival pathways and cell proliferation. This protein also interacts with amyloid precursor protein (APP) and suppresses the production of amyloid beta (Abeta). Multiple alternatively spliced transcript variants encoding different isoforms have been identified.
Research relevance and current trends
- Comparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).
- Subcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.
- Integration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.
Common research applications
- Western blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- Immunohistochemistry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- Immunofluorescence: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- Flow cytometry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- ELISA: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
Interpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.
Notes for experimental interpretation
- Isoforms and PTMs: many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands/signals accordingly.
- Epitope context: binding can depend on protein conformation and sample processing; region information in the title/immunogen can help anticipate what may be detected.
- Species differences: predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.
- Control concepts: include negative controls (no-primary/isotype), and where possible genetic controls (KO/KD) or independent antibodies to strengthen conclusions.
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).
