Overview
Recognizes a cell surface glycoprotein of 80-95kDa (CD44) on lymphocytes, monocytes, and granulocytes. Its epitope is resistant to digestion by trypsin and chymotrypsin. The CD44 family of glycoproteins exists in a number of variant isoforms, the most common being the standard 85-95kDa or hematopoietic variant (CD44s). Higher molecular weight isoforms are described in epithelial cells (CD44v), which are believed to function in intercellular adhesion and stromal binding. CD44 immunostaining is commonly used for the discrimination of urothelial transitional cell carcinoma in-situ from non-neoplastic changes in the urothelium.
This anti-CD44 antibody is supplied as Purified (Mouse, Monoclonal (mouse origin), clone SPM544, Mouse IgG2a, kappa, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.
Key elements and design rationale
- Target: CD44
- Format: Purified
- Localization: Cell surface, cytoplasmic
- Species reactivity: Human
- Applications (listed): WB, IHC-P
- Conjugate: Unconjugated
- Clone and antibody class: Monoclonal (mouse origin), clone SPM544, Mouse IgG2a, kappa
Because antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.
Biological background
CD44 is referenced in public gene/protein resources (e.g., UniProt and NCBI Gene), which provide curated names/synonyms, protein features, and pathway context. When designing assays, consider potential isoforms, post-translational modifications, and cell-type specific expression that may influence observed signal.
Research relevance and current trends
- Profiling CD44 expression across model systems, perturbations, and time points to support mechanistic hypotheses.
- Combining antibody-based detection with multi-omics or imaging readouts to link CD44 signal with phenotype.
- Using well-matched controls (isotype controls, genetic perturbations, or independent reagents) to strengthen interpretation of target-associated signal.
Common research applications
- WB
- IHC-P
Use the listed applications as a starting point and tailor experimental design to your sample type and readout requirements.
Notes for experimental interpretation
- Specificity considerations: closely related family members, isoforms, or PTMs can affect apparent specificity; confirm with independent approaches when critical.
- Controls: include negative controls and, when feasible, genetic or pharmacologic perturbations to support target attribution in your system.
- Species and sample context: differences in sequence, expression, fixation, or extraction conditions can change signal behavior across models.
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).
