Description: GGPS1(Geranylgeranyl pyrophosphate synthase) belongs to the FPP/GGPP synthase family and catalyzes the synthesis of GGPP, an important molecule responsible for the C20-prenylation of protein and for the regulation of a nuclear hormone receptor. GGPP synthase puri¢ed from bovine brain is reported to be a homo-oligomer (150-195 kDa) with a molecular mass of 37.5 kDa for the monomer.This is consistent with the calculated molecular mass (35 kDa) of mouse and human GGPP synthases .

Description: Chloroform is typically used as a solvent and as a cleansing agent. Procedures have been described for the use of chloroform in lambda plaques storage, lambda cDNA storage, the removal of mineral oil from PCR reaction samples, oligonucleotide purification, a hydroxyl radical footprinting protocol, a transcriptional run-on assay protocol, and an overlay assay for beta-galactosidase activity. It has also been used with phenol in such procedures as DNA recovery from polyacrylamide gels, ethidium bromide removal from DNA preparations, lysis protocols for plasmid DNA isolation, RNase removal, and purification of yeast DNA. A protocol describes the use of chloroform in a high-performance thin-layer chromatography protocol for sphingomyelin analysis. Chloroform can also be used in chloroform/methanol mixtures for the isolation of cardiolipids from Geobacillus stearothermophilus and their subsequent MS analysis. The isolation of the bacteriocin amylovorin L471 from Lactobacillus amylovorus DCE 471 in culture broth has been reported, using chloroform/methanol extraction and precipitation in the procedure. Chloroform/2-butanol mixtures can be used for the extraction of steroid sulfates for analysis by nanoelectrospray ionization mass spectrometry.

Description: MDM4 is also named as MDMX. It inhibits the activity of the tumor suppressor p53 by primarily cooperating with the p53 feedback regulator MDM2. MDM4 resides mostly in the cytoplasm, but can be recruited to the nucleus by MDM2.. The predicted mass of the protein is 54 kD, while the observed mass is 80 kD, a difference which stated is probably due to phosphorylation or other posttranslational modification. It can be ubiquitinated and degraded by MDM2. It has 5 isoforms produced by alternative splicing.

Description: OX40L, a member of the TNF superfamily of structurally related proteins, exists primarily as a type II membrane-bound, non-covalently linked, homotrimeric protein. It is expressed on antigen-presenting cells (APCs), such as dendritic cells and activated B-cells, as well as on various other cells such as vascular endothelial cells, mast cells, and natural killer cells. OX40L signals specifically through the OX40 receptor, which is expressed predominantly on CD4+ T cells, but also on certain activated CD8+ T cells. OX40/OX40L functions as a costimulatory signal, which is required for a productive interaction between antigen-presenting cells and their target T-cells. It enhances cell proliferation and survival, and increases expression of RANTES, IL-2, IL-3, and IFNγ. OX40/OX40L signaling plays an important role in immuno-regulatory communication, enabling the immune system to distinguish between “friend vs. foe” during activation; a mechanism typically termed immuno-tolerance. Recombinant Human sOX40 Ligand is a glycosylated 133 amino acid protein corresponding to the extracellular TNF homologous domain of the full length transmembrane protein. It migrates with an apparent molecular mass of 15.5 – 25.0 kDa on SDS-PAGE. Recombinant Human sOX40 Ligand has a calculated, theoretical molecular weight of 15.4 kDa.

Description: Matrix Metalloproteinases (MMPs) are a large family of endopeptidases. Collectively, MMPs can degrade all kinds of extracellular matrix proteins, and can also process a number of bioactive molecules. They are known to be involved in the cleavage of cell surface receptors, the release of apoptotic ligands, and chemokine/cytokine inactivation. MMPs are also thought to play a major role in cell behaviors such as cell proliferation, migration (adhesion/dispersion), differentiation, angiogenesis, apoptosis, and host defense.
This peptide is an exceptional MMP-2 (gelatinase A) and MMP-9 (gelatinase B) substrate: this peptide is used for the continuous spectrophotometric assay of MMP-2 and MMP-9 in combination with a color-developing thiol-reactive agent, 4,4’-dithiodipyridine or Ellman’s Reagent (as indicators). This thiol peptide-enzyme reaction has a Km of 0.004 M and a kcat of 103 s-1. Using this substrate, collagenase can be detected at concentrations as low as 2 ng/mL. HPLC and tandem mass spectrometry are also used to analyze MMP-2 and MMP-9 in conjunction with this peptide substrate.
