Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Immunohistochemistry on fresh frozen (IHC-Fr) cryo-tissue-sections. In contrast to standard PFA perfusion fixed tissues, fresh frozen cryo-tissue-sections can be variably postfixed with alcohols, acetone or PFA. Alcohol or acetone fixation is e.g. of advantage for antigens masked by PFA crosslinking. For recommended postfixation, please refer to the ”Remarks” section. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Immunohistochemistry on glyoxal fixed (IHC-G) tissue. The tissue is perfused with saline and afterwards immersion fixed with a glyoxal solution. For details of the glyoxal solution, please refer to the remarks section. Immunoreactivity is usually revealed by fluorescence.

Immunogen Synthetic peptide corresponding to residues near the carboxy terminus of rat ATP13A5 (UniProt Id: F1MA70)
Reactivity Reacts with: human (Q4VNC0), rat (F1MA70), mouse (Q3TYU2).
Other species not tested yet.
Remarks

IHC: This antibody requires mild fixation.
IHC-Fr: Formaldehyde or Acetone fixation are recommended.
IHC-G: Fixation with 3% glyoxal, 1% acetic acid, 20% ethanol in ddH2O according to Richter et al. 2017, or 9% glyoxal, 8% acetic acid in ddH2O according to Konno et al. 2023 are recommended.

Background

ATP13A5 is a marker that plays a key role in identifying central nervous system (CNS) pericytes, which are essential for vascular development and the maintenance of the blood-brain barrier (BBB). CNS pericytes are distinct from those in peripheral organs, and ATP13A5 has emerged as a specific genetic marker for these cells, validated through advanced transcriptomic and genetic models.
In mice, ATP13A5 expression is observed from embryonic day 15, aligning with the establishment of the BBB, and persists into adulthood, underscoring its role in CNS vasculature development. A knock-in model with ATP13A5-driven tdTomato reporter and Cre recombinase demonstrates that ATP13A5 expression is confined to CNS pericytes, including those in the brain, spinal cord, and retina, while showing minimal expression in peripheral tissues.
This marker enables precise genetic manipulation and detailed study of pericyte biology, including their development, heterogeneity, and function within the BBB. The specificity of ATP13A5 facilitates research into its role in neurological disorders, particularly those involving BBB dysfunction, such as Alzheimer's disease. The ATP13A5 model also supports the development of targeted therapies and genetic tools for studying CNS vascular health and disease (1).
