CD1A Antibody for IHC. Immunohistochemistry analysis of CD1A / CD1a expression in FFPE human skin tissue using CD1A Antibody. Membranous and cytoplasmic staining is observed in dendritic cells within the epidermis and superficial dermis, consistent with Langerhans cell localization, while surrounding keratinocytes remain largely negative. The presence of CD1a-positive cells at the epithelial interface reflects immune cell infiltration and supports evaluation of antigen-presenting dendritic cells within tissue microenvironments. HIER: boil tissue sections in pH 9 10 mM Tris with 1 mM EDTA for 20 minutes and allow to cool before testing.

Description

CD1 molecule alpha 1 (CD1A) is a transmembrane glycoprotein encoded by the CD1A gene that functions in lipid antigen presentation and is expressed on dendritic cells involved in immune surveillance. CD1A antibody, also known as CD1a antibody or T-cell surface glycoprotein CD1a antibody, enables detection of antigen-presenting cells within tumor-associated tissues. CD1A Antibody is particularly useful for evaluating dendritic cell infiltration within the tumor microenvironment and for characterizing immune cell composition in cancer tissues.

In solid tumors, dendritic cells play a central role in initiating anti-tumor immune responses by capturing tumor-derived antigens and presenting them to T cells. CD1a-positive dendritic cells are frequently located within tumor stroma, at invasive tumor margins, or in peritumoral regions, where they contribute to immune recognition and modulation of local immune activity. Detection of CD1a therefore provides insight into the presence, density, and spatial distribution of antigen-presenting cells within tumor tissues.

Immunohistochemical analysis of CD1a allows visualization of dendritic cell infiltration patterns across different tumor types, supporting evaluation of immune microenvironment heterogeneity. The abundance and localization of CD1a-positive cells can vary depending on tumor biology, stage, and immune status, making CD1A a useful marker for studying tumor-immune interactions. In some contexts, increased dendritic cell presence reflects active immune surveillance, while in others it may indicate altered or suppressed immune function within the tumor microenvironment.

CD1a expression can also be used to assess immune cell recruitment and activation in response to therapeutic interventions, including immunomodulatory treatments. Changes in CD1a-positive cell distribution may provide insight into how tumors interact with the immune system and how immune cell populations respond to external stimuli.

CD1A Antibody is therefore well suited for studies focused on tumor immune infiltration and microenvironment analysis. Its use supports identification of dendritic cells within tumor tissues and enables detailed investigation of immune cell distribution, tumor-associated immune responses, and the dynamics of antigen-presenting cell populations in cancer biology.

A full range of CD1A antibody reagents for immunohistochemistry, western blot, and flow cytometry is available on our CD1A Antibody collection page.
