Only our best-performing antibodies are designated as Picoband, ensuring unmatched performance.
Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: A synthetic peptide corresponding to a sequence at the N-terminus of human HLA A.
- Molecular weight context: reported MW: 41 kDa; calculated MW: 40922 MW
- Reactivity: Human
- Applications: IF, IHC, ICC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
HLA class I histocompatibility antigen, A-2 alpha chain; HLA class I histocompatibility antigen, A-2 alpha chain. HLA-A, namely HLA A, is a group of human leukocyte antigens (HLA) that are coded for by the HLA-A locus, which is located at human chromosome 6p21.3. HLA is simply the major histocompatibility complex (MHC) specific to humans. HLA-A is one of three major types of human MHC class I cell surface receptors. The others are HLA-B and HLA-C. And it is critical to the cytotoxic t-cell controlled immune response to viruses and other intracellular pathogens. Because each HLA-A gene has a high affinity for slightly different peptides, certain HLA-As are associated with increased risk, more rapid progression, and/or increased severity of many diseases. For similar reasons, HLA-A matching is essential to successful tissue transplants. Functional note: Involved in the presentation of foreign antigens to the immune system. Reported localization: Membrane; Single-pass type I membrane protein. Expression/tissue context: Mainly expressed in brain with predominant expression is in the cerebellum, also present in the hippocampus, amygdala, caudate nucleus, corpus callosum, subthalamic nuclei and thalamus. Detected in the heart, skeletal muscle and pancreas.

Common research applications
- Western blotting: compare relative HLA-A (HLA class I histocompatibility antigen, A-2 alpha chain) levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of HLA-A (HLA class I histocompatibility antigen, A-2 alpha chain) across tissue regions and cell types using matched controls.
- IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Family / similarity context: Belongs to the MHC class I family.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
