After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.

Description

The development of the FDFT1 recombinant monoclonal antibody involves four steps: first, sequencing the FDFT1 monoclonal antibody gene, then cloning the gene into a plasmid vector, followed by the transfection of the recombinant vector into a host cell line, and final purification of the FDFT1 recombinant monoclonal antibody from the cell culture supernatant using affinity chromatography. The FDFT1 monoclonal antibody is derived from FDFT1 antibody-producing hybridomas, with a synthesized peptide derived from human FDFT1 used as the immunogen. This FDFT1 recombinant monoclonal antibody is highly recommended for use in ELISA, WB, and IHC applications for the detection of human FDFT1 protein.

The FDFT1 protein, also known as squalene synthase, plays a key role in cholesterol biosynthesis in cells. Specifically, FDFT1 catalyzes the synthesis of squalene from farnesyl pyrophosphate and is the first committed step in the cholesterol biosynthesis pathway. Squalene is then converted into cholesterol through a series of enzymatic reactions. FDFT1 is primarily found in the endoplasmic reticulum of cells and is highly expressed in liver and steroidogenic tissues. In addition to its role in cholesterol biosynthesis, FDFT1 has also been implicated in the regulation of cell proliferation and survival.

Target Background

Function
Catalyzes the condensation of 2 farnesyl pyrophosphate (FPP) moieties to form squalene. Proceeds in two distinct steps. In the first half-reaction, two molecules of FPP react to form the stable presqualene diphosphate intermediate (PSQPP), with concomitant release of a proton and a molecule of inorganic diphosphate. In the second half-reaction, PSQPP undergoes heterolysis, isomerization, and reduction with NADPH or NADH to form squalene. It is the first committed enzyme of the sterol biosynthesis pathway.

  3. Up-regulation of SQS promotes metastasis of lung cancer by enhancing tumor necrosis factor-alpha receptor 1 and nuclear factor-kappaB activation and matrix metallopeptidase 1 expression. PMID: 25152164
  4. Several critical residues that are involved in binding of NADPH have been identified in the active site of squalene synthase. PMID: 24531458
  5. HCV infection increases FDFT1 protein level but not FDFT1 mRNA level. PMID: 24690320
  6. this finding yields a new method of colorimetric screening for the cellular activity of squalene synthases, which are major targets for cholesterol-lowering drugs. PMID: 24333579

  11. In multivariate models adjusted for age, body mass index, diabetes, waist/hip ratios, and levels of glycated hemoglobin, the NAFLD activity score was associated with the SNP rs2645424 on chromosome 8 in farnesyl diphosphate farnesyl transferase 1 (FDFT1) PMID: 20708005
