  • 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

SPI1 / PU.1 antibody was raised against synthetic peptide C-DLYQRQTHEYY from an internal region of human SPI1 / PU.1 (NP_001074016.1; NP_003111.2). Percent identity by BLAST analysis: Human, Gorilla, Gibbon, Monkey, Panda, Bovine, Dog, Horse, Rabbit, Pig (100%); Marmoset, Opossum (91%); Rat, Platypus (82%).
LS-E26660 - Lyophilized - 100 µg - $145.00
Human SPI1 / PU.1. This antibody is expected to recognise both reported isoforms (NP_001074016.1; NP_003111.2).
Immunohistochemistry: LS-B3822 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-B3822 was determined to be 3.75ug/ml.


Tris-buffered saline, pH 7.3, 0.5% BSA, 0.02% sodium azide
Store at -20°C. Minimize freezing and thawing.

Binds to the PU-box, a purine-rich DNA sequence (5'-GAGGAA-3') that can act as a lymphoid-specific enhancer. This protein is a transcriptional activator that may be specifically involved in the differentiation or activation of macrophages or B-cells. Also binds RNA and may modulate pre-mRNA splicing.
