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.
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".

Recombinant human estrogen receptor (alpha form).
Recognizes the human estrogen receptor alpha chain (ERalpha), also known as the estradiol receptor or nuclear receptor subfamily 3 group A member 1. ERalpha is a ~65kD steroid hormone receptor containing an N-terminal. ligand independent transactivation domain, a DNA binding domain and a C-terminal ligand binding domain which overlaps with an. ERalpha binds to DNA as a homodimer and can also form heterodimers with Estrogen receptor beta The detection of estrogen (ER) and progesterone (PR) receptors using immunohistochemical staining of formalin fixed, paraffin embedded (FFPE) tissue, has gradually replaced ligand binding assays, to become the most common method for the determination of the ER/PR status of breast tumors. Approximately 75% to 80% of breast tumors have estrogen and/or progesterone receptors, and the presence of these receptors helps determine both the patients prognosis and the effectiveness of hormonal therapy. Has been used successfully for identification of ERalpha on breast cancer cell lysates using Western blotting and for the immunohistochemical detection of ERalpha in breast cancer tissues.
Immunohistology: Zamboni's fixative recommended for best results. #This product requires antigen retrieval using heat treatment prior to staining of paraffin sections. Sodium citrate buffer pH6.0 is recommended for this purpose.
Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Ligand-dependent nuclear transactivation involves either direct homodimer binding to a palindromic estrogen response element (ERE) sequence or association with other DNA-binding transcription factors, such as AP-1/c-Jun, c-Fos, ATF-2, Sp1 and Sp3, to mediate ERE-independent signaling.
