  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

KCNJ2 / Kir2.1 antibody was raised against synthetic peptide amino acids 390-411 (cytoplasmic C-terminus) of mouse Kir2.1
Detects ~55 kD protein. No cross reactivity against Kir2.2, or Kir2.3.
Western Blot: Use the lysate in SDS buffer but without boiling, incubating for 20 mins at 37°C instead.


PBS, pH 7.4, 50% glycerol, 0.09% sodium azide

Probably participates in establishing action potential waveform and excitability of neuronal and muscle tissues. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages.
