Human recombinant TGF beta 3 (from E. coli)

Catalog Number: (PRSI40-574)
Supplier: ProSci Inc.
Description: The three mammalian isoforms of TGF-β, TGF-β1, β2, β3, signal through the same receptor and elicit similar biological responses. They are multifunctional cytokines that regulate cell proliferation, growth, differentiation and motility as well as synthesis and deposition of the extracellular matrix. They are involved in various physiological processes including embryogenesis, tissue remodeling and would healing. They are secreted predominantly as latent complexes which are stored at the cell surface and in the extracellular matrix. The release of biologically active TGF-β isoform from a latent complex involves proteolytic processing of the complex and /or induction of conformational changes by proteins such as thrombospondin-1. The physiological role of TGF-β3 is still unknown but its expression pattern suggests a role in the regulation of certain development processes. Recombinant TGF-β3 is a 25.0 kDa protein composed of two identical 112 amino acid polypeptide chains linked by a single disulfide bond.Manufactured using all non-animal reagents.

Anti-VIM Mouse Monoclonal Antibody [clone: SPM576]

Catalog Number: (PRSI34-182)
Supplier: ProSci Inc.
Description: This mAb reacts with a 58 kDa protein identified as vimentin. It shows no cross-reaction with other closely related intermediate filament proteins (IFPs) such as desmin, keratin, neurofilament, and glial fibrillary acid protein. Anti-vimentin alone is of limited value as a diagnostic tool; however, when used in panels with other antibodies, it is useful for the sub-classification of a given tumor. Expression of vimentin, when used in conjunction with anti-keratin, is helpful when distinguishing melanomas from undifferentiated carcinomas and large cell lymphomas. All melanomas and Schwannomas react strongly with anti-vimentin. It labels a variety of mesenchymal cells, including melanocytes, lymphocytes, endothelial cells, and fibroblasts. Non-reactivity of anti-vimentin is often considered more useful than its positive reactivity, since there are a few tumors that do not contain vimentin, e.g. hepatoma and seminoma. Anti-vimentin is also useful as a tissue process control reagent.

L(-)-Glutathione (reduced form) ≥98%, off-white powder cell culture reagent

Supplier: MP Biomedicals
Description: Storage: Store at +4 °C, store under nitrogen
Glutathione is the major low molecular weight thiol compound of the living plant or animal cell. It is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. The sulfhydryl (thiol) group (SH) of cysteine serves as a proton donor and is responsible for the biological activity of glutathione.
Glutathione suppresses human immunodeficiency virus expression in chronically infected monocytic cells. It is a useful tripeptide involved in many aspects of metabolism, including transport of g-glutanyl amino acids and reductive cleavage of disulfide bonds.
Endogenous antioxidant that plays a major role in reducing reactive oxygen species formed during cellular metabolism and the respiratory burst. Glutathione-S-transferase catalyzes the formation of glutathione thioethers with xenobiotics, leukotrienes, and other molecules that have an electrophilic center. Glutathione also forms disulfide bonds with cysteine residues in proteins. Via these mechanisms, it can have the paradoxical effect of reducing the efficacy of anti-cancer agents.

PerfeCTa® PreAmp 5X SuperMix

Catalog Number: (733-2265)
Supplier: Quantabio
Description: PerfeCTa® PreAmp SuperMix is a 5X concentrated, ready to use reaction cocktail for unbiased, selected enrichment of target sequences from limited amounts of starting material for downstream gene expression profiling or targeted resequencing. It contains all components, except primers and templates. The 5X concentrated SuperMix allows addition of higher template volumes when working with low concentration samples, and/or reduced reaction volumes. Inclusion of an inert light blue tracer dye helps visualise small reaction volumes and ensure accurate pipetting.

Ultra-Plex™ 1-Step ToughMix® (4X)

Supplier: Quantabio
Description: Ultra-Plex™ 1-Step ToughMix® is a ready-to-use, 4X-concentrated master mix for reverse transcription quantitative PCR (RT-qPCR) of RNA templates using hybridisation probe detection chemistries such as TaqMan® 5’-hydrolysis probes on Real-Time PCR systems that utilise ROX passive reference with 490 nM excitation. First-strand cDNA synthesis and PCR amplification are carried out in the same tube without opening between procedures. It is ideal for highly sensitive quantification of RNA viruses or low abundance RNA targets in uni- or multiplexed RT-qPCR applications as well as high throughput gene-expression studies. The system has been optimised to deliver maximum RT-qPCR efficiency, sensitivity, and specificity in reduced reaction volumes and fast cycle times. Ultra-Plex™ 1-Step ToughMix® contains all required components for RT-qPCR except RNA template and probe. It is compatible with all dual-labeled probe chemistries.

PCR cloning kit, CloneJET

Supplier: Thermo Fisher Scientific
Description: The CloneJET PCR cloning kit contains a ready-to-use positive selection cloning vector pJET1.2/blunt. The vector contains a lethal restriction enzyme gene that is disrupted by ligation of a DNA insert into the cloning site. As a result, only bacterial cells with recombinant plasmids are able to form colonies. Recircularised pJET1.2/blunt vector molecules lacking an insert express a lethal restriction enzyme, which kills the host <i>E. coli</i> cell after transformation. This positive selection drastically accelerates the process of colony screening and eliminates additional costs required for blue/white selection.

Folin-Ciocalteu's reagent 1,9 - 2,1 N for analysis of phenols, suitable for determination of total protein by Lowry method, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Folin & Ciocalteu's phenol reagent is most commonly used in the Lowry method for determining protein concentration. It has also been used for the quantification of total phenolics. In this method, protein is pretreated with copper(II) in a modified biuret reagent (alkaline copper solution
stabilized with sodium potassium tartrate). Addition of the phenol reagent generates chromogens that give increasing absorbance between 550-750nm. Normally, absorbance at the peak (750 nm) or shoulder (660 nm) are used to quantitate protein concentrations between 1 - 100 mg/ml while absorbance at 550 nm is used to quantitate higher protein concentrations.
