A disulfide with antitumor and antiplatelet activities; cytotoxic to a variety of cancer cells (IC50s = 7-38 µM); reduces tumor growth and decreases the number of lung metastases in murine models of melanoma at 25 mg/kg; prevents thrombus formation in heparinized animals in a porcine model of severe vascular damage at 25 mg/kg
Biotium Methicillin Resistant Staphylococcus Aureus (MRSA) (332/423), CF594 conjugate, 0.1mg/mL
Staphylococcal enterotoxins represent a group of proteins, which are secreted by Staphylococcus aureus and cause the intoxication staphylococcal food poisoning syndrome. The illness characterized by high fever, hypotension, diarrhea, shock, and in some cases death. Their molecular masses range between 27 and 30 kDa. At present, seven enterotoxins are known, namely A, B, C1, C2, C3, D and E. Their amino acid sequences have been determined and it was shown that all are single chain polypeptides containing one disulfide bond formed by two half cysteine located in the middle of the polypeptide chain, which form the so called cysteine loop. Enterotoxins are extremely potent activator of T cells, stimulating the production and secretion of various cytokines, which mediate many of the toxic effects of these substances. Enterotoxins are super antigens, inducing polyclonal T cell activation by binding to the TCR and to the alpha chain of the MHC II molecule simultaneously.Primary an
Medchemexpress LLC Protease 7/OmpT E.c 100ug
Protease 7 (OmpT) is a recombinant Escherichia coli outer-membrane protease supplied as a His-tagged, lyophilized protein for research applications. It preferentially cleaves substrates with paired basic residues and is used in proteolytic assays, substrate specificity studies, and protein processing workflows. The formulation and handling guidance support activity preservation during storage and use.
- Recombinant Escherichia coli OmpT protease with His tag.
- High purity (>90%) as determined by reducing SDS-PAGE.
- Lyophilized formulation in Tris-EDTA with trehalose for stability.
- Approximate molecular weight 37.5 kDa and full amino acid sequence available.
- Reconstitution recommended at ≥100 μg/mL in ddH2O; stable at 4°C for one week after reconstitution.
- Store lyophilized at -20°C; freeze aliquots at -20°C or -80°C for long-term storage.

Sigma Aldrich Fine Chemicals Biosciences Microbial DNA standard fro
Standardization of sample analysis is currently needed in microbiome genomics research workflow. Lack of standardization can lead to biases and errors in common processes during sample preparation and analysis such as sample amplification sequencing and bioinformatics analyses. Pseudomonas Aeruginosa genomic DNA microbial standard can serve as standard for benchmarking the performance along the workflow of microbiomics or meta-genomics analyses and as a tool to increase reproducibility and allow comparison of results obtained by different labs. Pseudomonas aeruginosa is a gram negative aerobic to facultative anaerobe rod shaped bacteria which commonly inhabits soil and aqueous environments. In cases of a compromised immune system Pseudomonas aeruginosa can be an opportunistic pathogen. Its devastating effect is mostly known in Cystic fibrosis (Cf) patients. in addition it often poses a major problem in burn wounds chronic wounds and in chronic obstructive pulmonary Disorder (COPD).
