  • 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

MRGPRX2 / MRGX2 antibody was raised against synthetic 16 amino acid peptide from 3rd extracellular domain of human MRGPRX2 / MRGX2. Percent identity with other species by BLAST analysis: Human (100%); Chimpanzee, Gorilla, Monkey (94%); Orangutan (88%); Gibbon (81%).
LS-E29161 - Liquid - 50 µg 1 mg/ml - $145.00
Immunizing peptide used to generate LS-A6645. Useful for pre-absorption and neutralization of the antibody's antigen binding site.
Extracellular Domain
Human MRGPRX2 / MRGX2. BLAST analysis of the peptide immunogen showed no homology with other human proteins, except MRGPRX1 (56%), MRGPRX3 (50%).
Immunohistochemistry: LS-A6645 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for LS-A6645 was determined to be 20 ug/ml.


PBS, less than 0.1% sodium azide.
Aliquot and store undiluted at -20°C or below for up to 1 year. Can be stored undiluted at 4°C for up to 1 month. Avoid freeze thaw cycles.
For research use only.

MRGPRX2 Antibody, MRGX2 Antibody, MAS-related GPR, member X2 Antibody

Orphan receptor. Probably involved in the function of nociceptive neurons. May regulate nociceptor function and/or development, including the sensation or modulation of pain. Cortistatin-14 seems to be a high potency ligand at this receptor. Cortistatin has several biological functions including roles in sleep regulation locomotor activity, and cortical function.


Anti-MRGPRX2 / MRGX2 antibody LS-A6645 IHC of human spinal cord, dorsal root ganglion. Immunohistochemistry of formalin-fixed, paraffin-embedded tissue after heat-induced antigen retrieval.
