Request a P53 in cancer poster

P53 is an important factor for tumour suppression and is activated under cellular stress (e.g., DNA damage) to induce cell cycle arrest or apoptosis. p53 mutants found in tumours are no longer functional as tumour suppressors, resulting in cell malignancies. The immune response in tumour patients correlates with the presence of p53 mutations, which leads to the accumulation of ineffective p53 proteins in the tumour cells. Anti-p53 autoantibodies are produced in many types of tumours and can be detected during early tumour stages compared to conventional tumour marker detection. Autoantibody signatures in cancer, such as anti-p53 antibodies, are potential tumour biomarkers.

Anti-p53 ELISA Test Kit, 48 well, Product Code RG-7640E

IDH antibodies

Human isocitrate dehydrogenases (IDHs) are classified into three subtypes: IDH1, IDH2 and IDH3. IDH1 mutations have been found in patients with acute myeloid leukaemia, while IDH1/2 mutations have been found in multiple stages of brain tumours such glioma and glioblastoma. The mutant forms of IDH1 appear in 90% of patients with glioma while the mutant forms of IDH2 appear in 50% of patients, making IDH1/2 mutations a useful marker for prognosis of glioma. MBLI offers highly specific antibodies to mutant forms of IDH1 (R132H, R132S, R132G) and IDH2 (R172K, R172M, R172W) which can be used to detect mutated IDHs in specimens of low tumour occupancy.

AMP-Activated Protein Kinase (AMPK) regulates cellular energy metabolism by modulating the activity of key enzymes such as acetyl-coenzyme A carboxylase (ACC) and mTOR (mammalian target of rapamycin) in metabolic pathways through their phosphorylation and of transcription factors and cofactors. AMPK stimulates energy-producing pathways (e.g., glucose transport, fatty acid oxidation), and turns off energy-consuming pathways (e.g., protein synthesis, lipogenesis, gluconeogenesis). Adiponectin and leptin as well as hypoglycemic drugs are known as activators of AMPK in adipose tissues. The activation of AMPK occurs upon fasting and exercise which involve changes in the AMP/ATP ratio and the primary upstream liver kinase B1 (LKB1). AMPK is the target of metformin and hormones which improve insulin sensitivity and may serve as the target of pharmaceuticals involved in insulin resistance (type 2 diabetes).

MBLI has a wide portfolio of immune monitoring research products including tetramer technology for vaccine development, rapid T-cell detection and quantification in the pharmaceutical industry or bioresearch industry.

Major Histocompatibility Complex (MHC) tetramer technology utilizes the MHC/peptide complex to detect antigen specific T cells at the single-cell level, thus surpassing detection limits of traditional cell-based methods. MHC tetramer technology is the most accurate method for detection of rare events. The information MHC tetramers provide is pivotal the direct development of vaccines and therapies, as well as monitoring patient response during clinical trials. To greatly reduce non-specific binding, Class I iTAgTM MHC Tetramers specific to human alleles have a proprietary mutation in the α3 domain.

Graft-versus-host disease (GVHD) is a common complication associated with HSCT. GVHD occurs when transplanted immune cells recognize the recipient as "foreign" creating an immune response where the transplanted cells attack the host cells. In addition to providing MHC Tetramers.

 which can be used to monitor assess CMV risk in transplant patients, MBLI offers several GVHD biomarkers including: CRP, Elafin, IL-18, Lactoferrin, REG3alpha and ST2.

Interleukin-18 (IL-18) is a cytokine produced by dendritic cells, monocytes, macrophages, neutrophils, and epithelial cells. Th1-type immunoreactions are facilitated primarily by IL-18. Furthermore, action of IL-18 on basophils and mast cells cause complex physiological responses, including allergic reactions. High levels of IL-18 are detected in the blood of patients with allergic and autoimmune diseases. IL-18 is also found in the urine of patients with acute renal disorder and mediates the progression of type 2 diabetes.

Eosinophil Cationic Protein (ECP) and Eosinophil Derived Neurotoxin (EDN) and Major Basic Protein (MBP) are known to be major protein-mediators derived from activated eosinophils. Activated eosinophils play an important role in inflammatory processes especially in allergic diseases. The levels of eosinophil activation can serve as complimentary data for monitoring asthma inflammation. As ECP/EDN proteins are secreted from activated eosinophils, they become markers of eosinophil activation and degranulation which can cause inflammatory disease of the airways.

Request an autophagy poster

Autophagy is a cellular self-digestion process for the purpose of providing nutrients to enable cells to survive starvation. Autophagy plays an important role in maintaining the cell homeostasis by removing cellular components that have degraded. Recent research has also shown an association of mammalian autophagy with pathological conditions including neurodegenerative diseases, infection, cardiac disease, cancer and aging.

LC3 plays an integral role as an autophagosome maker, because it resides in the entire process of autophagosome formation. Upon autophagy induction, LC3-I, a small and soluble cytoplasmic protein, is conjugated with a phospholipid which anchors it to the autophagosomal membrane as LC3-II. Autophagy can be induced by nutrient deprivation. Our polyclonal and monoclonal antibodies can be used to quantify LC3-I and LC3-II levels within the cell.

Fluorescent Proteins

FUCCI (Fluorescent Ubiquitination-based Cell Cycle Indicator) is a set of fluorescent probes which enable the visualization of cell cycle progression in living cells. FUCCI takes advantage of the fact that the replication licensing factors Cdt1 and Geminin are only present during specific phases of the cell cycle. A fusion protein of a fragment of Cdt1 (amino acids 30-120) with the fluorescent protein monomeric Kusabira-Orange 2 (mKO2) serves as an indicator of G1 phase, while a fusion protein of a fragment of Geminin (amino acids 1-110 or 1-60) with the fluorescent protein monomeric Azami-Green 1 (mAG1) visualizes S, G2 and M phase. The cell cycle indicator takes advantage of the highly selective, rapid degradation of the replication licensing factors, mediated by the ubiquitin-proteasome system.

Request a cholesterol-cardiovascular pathway poster

PCSK9 is an extracellular protein expressed primarily in the kidneys, liver and intestines representing the 9th member of the secretory subtilase family. PCSK9 plays a major role in cholesterol metabolism through posttranslational down-regulation of LDLR, the receptor responsible for clearing LDL-C from plasma. PCSK9 binds directly to first epidermal growth factor-like repeat A (EGF-A) domain of LDLR and is required for LDLR degradation. PCSK9 would seem to be an attractive drug target for lowering LDL-C.
