  • 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

S. frugiperda insect ovarian cell line Sf21-derived recombinant human Follistatin Gly30-Asp329 Accession # P19883.
Detects human Follistatin in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross-reactivity with recombinant mouse.
Western Blot, 0.1 µg/ml, Recombinant Human Follistatin 300 aa 30-329. Immunohistochemistry, 5-15 µg/ml, Immersion fixed paraffin-embedded sections of human placenta. Neutralization, Measured by its ability to neutralize Follistatin inhibition of Activin A-dependent hemoglobin expression in the K562. human chronic myelogenous leukemia cell line. At 6 µg/ml, this antibody will neutralize approximately 60-85% of rhFollistatin 300 bioactivity on K562 cells.


Lyophilized from 0.2 um filtered solution in PBS, trehalose
Sterile PBS. Resuspend to 500 ul
Short term: 4°C. Long term: Store at -20°C. Avoid freeze-thaw cycles.

About FST / Follistatin

P19883 NM_006350 NP_006341.1

FST Antibody, Activin-binding protein Antibody, Follistatin isoform FST317 Antibody, Follistatin Antibody, Fs Antibody

Follistatin is a single-chain gonadal protein that specifically inhibits follicle-stimulating hormone release. The single FST gene encodes two isoforms, FST317 and FST344 containing 317 and 344 amino acids respectively, resulting from alternative splicing of the precursor mRNA. In a study in which 37 candidate genes were tested for linkage and association with polycystic ovary syndrome (PCOS) or hyperandrogenemia in 150 families, evidence was found for linkage between PCOS and follistatin.


Follistatin Inhibition of Activin A-induced Hemoglobin Expression and Neutralization by Human Follistatin Antibody. Recombinant Human Follistatin 300 inhibits Recombinant Human/Mouse/Rat Activin A induced hemoglobin expression in the K562 human chronic myelogenous leukemia cell line in a dose-dependent manner (orange line), as measured by psuedoperoxidase activity. Inhibition of Recombinant Human/Mouse/Rat Activin A (7.5 ng/ml) activity elicited by Recombinant Human Follistatin 300 (0.4 ug/ml) is neutralized (green line) by increasing concentrations of Goat Anti-Human Follistatin Antigen Affinity-purified Polyclonal Antibody. At 6 ug/m L, this antibody will neutralize approximately 60-85% of rhFollistatin 300 bioactivity.
