Catalog Number: (PRSI91-777)
Supplier: ProSci Inc.
Description: Cell Growth Regulator with EF Hand Domain Protein 1 (CGREF1) is a secreted calcium ion binding protein. CGREF1 contains two EF-hand domains and both EF-hands are required for function. Human CGREF1 is synthesized as a 301 amino acid precursor that contains a 19 amino acid signal sequence, and a 282 amino acid mature chain. CGREF1 is probably digested extracellularly by an unknown serine protease generating extremely hydrophobic bioactive peptides. CGREF1 mediates cell-cell adhesion in a calcium-dependent manner. In addition, CGREF1 is able to inhibit growth in several cell lines.

Catalog Number: (PRSI34-189)
Supplier: ProSci Inc.
Description: Recognises a cell surface glycoprotein of 80-95 kDa (CD44) on lymphocytes, monocytes, and granulocytes. Its epitope is resistant to digestion by trypsin and chymotrypsin. The CD44 family of glycoproteins exists in a number of variant isoforms, the most common being the standard 85 to 95 kDa or hematopoietic variant (CD44s). Higher molecular weight isoforms are described in epithelial cells (CD44v), which are believed to function in intercellular adhesion and stromal binding. CD44 immunostaining is commonly used for the discrimination of urothelial transitional cell carcinoma in-situ from non-neoplastic changes in the urothelium.

Catalog Number: (K1441)
Supplier: Thermo Fisher Scientific
Description: 5-Methylcytosine is a prominent epigenetic DNA modification which plays an important role in regulation of gene expression. The EpiJET™ DNA Methylation Analysis Kit (MspI/HpaII) uses the MspI and HpaII restriction enzymes to analyse DNA methylation status at a specific locus. Epi MspI and Epi HpaII are isoschizomers with differing sensitivities to CpG methylation. When the internal CpG in the 5’-CCGG-3’ tetranucleotide sequence is methylated, cleavage with Epi HpaII is blocked, but cleavage with Epi MspI is not affected. The Epi MspI and Epi HpaII enzymes are specially formulated for epigenetics studies to complete genomic DNA digestion in 1 hour.

Description: CELLvo™ Healthy Human Chondrocytes (50-70y) are primary, uncultured cells isolated from recently-diseased cadaver cartilage from donors between 50 and 70 years old. Healthy status is determined by macroscopic inspection of the tissue using a modified Outerbridge (1960) scale in order to distinguish healthy joints from those with signs of osteoarthritis. Cells are isolated by enzymatic digestion prior to cryopreservation.

Description: ERO1-Like Protein alpha (ERO1L) is an enzyme that belongs to the EROs family. ERO1L is expressed at high level in esophagus and upper digestive tract. ERO1L is an essential oxidoreductase that oxidizes proteins in the endoplasmic reticulum to produce disulfide bonds. ERO1L acts by oxidizing directly P4HB/PDI isomerase through a direct disulfide exchange. It associates with ERP44, demonstrating that it does not oxidize all PDI related proteins and can discriminate between PDI and related proteins. Its reoxidation probably involves electron transfer to molecular oxygen via FAD. ERO1L may be responsible for a significant proportion of reactive oxygen species (ROS) in the cell. ERO1L responses to temperature stimulus, protein thiol-disulfide exchange, protein folding with or without chaperone cofactor and transport.

Description: Proteinase K is a highly active stable endopeptidase with a broad spectrum of action was isolated by E. Merk's Darmstadt Biochemical Research Department in 1970 from a culture filtrate of the fungus, Tritirachium album Limber. This fungus is able to grow on Keratin (e.g., wool, horn particles) as the sole source of carbon and nitrogen. The isolated protease was, therefore, given the K designation.
Proteinase K is a stable and highly reactive serine protease. Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, detergents (SDS), and temperature. In the presence of 0,1 to 0,5% SDS, proteinase K retains activity and will digest a variety of proteins and nucleases in DNA preparations without compromising the integrity of the isolated DNA.

Description: Salusins are multifunctional bioactive peptides discovered by bioinformatics analyses of a full-length cDNA library. Salusin alpha and salusin beta are related peptides of 28 and 20 amino acids that were recently characterized. These peptides are considered to be biosynthesized from preprosalusin, an alternative-splicing product of the torsion dystonia-related gene (TOR2A), after frameshift reading and digestion at dibasic amino acids. Salusin alpha has recently been shown to be involved in atherosclerosis; it potently suppresses acyl-CoA:cholesterol acyltransferase-1 which stores cholesterol ester converted from free cholesterol in macrophages, thereby reducing human macrophage foam cell formation.

Description: This antibody recognises a cell surface glycoprotein of 80 to 95 kDa, called CD44, or HCAM, on lymphocytes, monocytes, and granulocytes (Leucocyte Typing Workshop V). Its epitope is resistant to digestion by trypsin and chymotrypsin. The CD44 family of glycoproteins exists in a number of variant isoforms, the most common being the standard 85 to 95 kDa or hematopoietic variant (CD44-s). Higher molecular weight isoforms are described in epithelial cells (CD44-v), which are believed to function in intercellular adhesion and stromal binding. HCAM antibody immunostaining is commonly used for the discrimination of urothelial transitional cell carcinoma in-situ from non-neoplastic changes in the urothelium.

Description: DreamTaq™ Green DNA Polymerase is a combination of DreamTaq™ DNA Polymerase and 10X DreamTaq™ Green Buffer. DreamTaq™ DNA Polymerase is an enhanced Taq DNA polymerase optimised for high throughput PCR applications. It ensures higher sensitivity, longer PCR products and higher yields compared to conventional Taq DNA polymerase.
DreamTaq™ Green DNA Polymerase incorporates modified nucleotides, but is inhibited by dUTP. The 10X DreamTaq™ Green Buffer includes a density reagent and two tracking dyes for direct loading of PCR products on a gel. The coloured buffer does not interfere with PCR performance and is compatible with downstream applications such as DNA sequencing,
phosphorylation, ligation and restriction digestion. For applications that require PCR product analysis by absorbance or fluorescence excitation, it is recommended either to use colourless 10X DreamTaq™ Buffer or purify the PCR product prior to analysis.

Description: Elastases form a subfamily of serine proteases that hydrolyze many proteins in addition to elastin. Humans have six genes which encode the structurally similar proteins: Elastase 1, 2, 2A, 2B, 3A, and 3B. Unlike other elastases, 3B has little elastolytic activity. Like most of the human elastases, 3B is secreted from the pancreas as a zymogen and, like other serine proteases such as trypsin, chymotrypsin and kallikrein; it has a digestive function in the intestine. Elastase 3B preferentially cleaves proteins after alanine residues. It may also function in the intestinal transport and metabolism of cholesterol. Elastases 3A/B have been referred to as Protease E and as Elastase 1, and excretion of this protein in fecal material is frequently used as a measure of pancreatic function in clinical assays.
