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".
SIRT1 Protein, SIR2-like protein 1 Protein, SIR2alpha Protein, SIR2L1 Protein, Sirtuin 1 Protein, Sir2-like 1 Protein, Sirtuin type 1 Protein, HSIR2 Protein, HSIRT1 Protein
The SIRT family of genes are highly conserved from prokaryotes to eukaryotes and are involved in diverse processes including transcriptional regulation, cell cycle progression, DNA damage repair and aging. Sirtuins utilize NAD+ as a substrate to catalyze deacetylation of specific acetylated protein and histones. SIRT1 has been shown to be induced by caloric restriction (CR) in several tissues and SIRT1 mediated deacetylase activity attenuates B-amyloid content in the brain during CR.
HDAC activity (HDAC Fluorimetric Assay -AK-500 from ELS). This assay is performed in two stages. In the first stage, the HDAC(s) acts on the Substrate (10 uM, 50 uM) (total volume of 50 ul). The second stage, is initiated by the addition of 50 ul of developer, stops HDAC activity and produces the fluorescent signal. The samples are read in a microplate reading fluorimeter, capable of excitation at a wavelength in the range 350~380nm and detection of emission light in the range 440~460nm.
The effect of resvertrol on recombinant human Sirtuin1 activity. hSirt1 (AG-40A-0117): 1 ug (0.25 ug/ml), NAD+ : 200 uM Substrate: flour de Lys, 50 uM.
Inhibition of Sirtuin1 activity by nicotinamide. Substrate: flour de Lys, 50 uM, NAD+ : 200 uM.
