Ubpbio 100X RELAYTR Europium/Cy5 Ubiquitin Mix, 200 x 20 µl Reactions

Time resolved (TR)-FRET offers a sensitive, low background, stable and homogenous assay for determination of protein ubiquitination. Europium-ubiquitin and Cy5-ubiquitin are a pair of modified ubiquitin suitable for TR-FRET assays to assess formation of polyubiquitin chains, thereby reporting the activity of E2 and E3 enzymes in the reaction. The concentration and molar ratio of europium-ubiquitin and Cy5-ubiquitin in the RELAYTR Europium/Cy5 Ubiquitin Mix are optimized to achieve excellent signal-to-background ratio in ubiquitination reactions. Optimization of protein concentrations is often necessary to achieve a desirable signal-to-background ratio. Typical protein concentration ranges are: UbE1 (10-30 nM), E2 (25-250 nM) and E3 (10-250 nM).Reaction time is usually 1-3 hours in kinetic or end point assay.

Gold Biotechnology Inc Hygromycin B 2.5 g

Hygromycin B is an aminoglycoside antibiotic isolated from Streptomyces hygroscopicus. It is commonly used to study protein synthesis. Aside from its efficacy against bacteria, fungi, and higher eukaryotic cells, hygromycin B is also an antiviral agent inhibiting translation upon selectively entering cells made permeable due to viral infection. It works as a standard selection antibiotic in gene experiments, especially for selection of hygromycin resistance gene transformed cells.

Alkali Scientific Carbenicillin, Disodium Salt, 5 G

Carbenicillin Disodium Salt is a beta-lactam antibiotic widely used in microbiology and molecular biology for selective inhibition of bacterial growth. It acts by disrupting cell wall synthesis, leading to bacterial cell death. Carbenicillin is frequently used in cloning and transformation experiments to maintain plasmid selection in bacterial cultures. It is more stable than ampicillin and reduces the formation of satellite colonies, ensuring clearer selection results. This compound is suitable for use in laboratory media and cell culture applications where consistent antibiotic activity is required. It supports research involving genetic engineering, microbial growth control, and studies of antibiotic resistance mechanisms.

Alkali Scientific Hygromycin B Liquid, 5 Vials

Hygromycin B is an antibiotic used as a selective agent in cell culture systems, particularly for eukaryotic cell lines and microbial selection. It inhibits protein synthesis by binding to the ribosome and disrupting the elongation cycle, which leads to cell death. This liquid formulation, containing 5 vials of Hygromycin B, is commonly used in genetic research to select for cells that have been genetically modified to express resistance to this antibiotic. Hygromycin B is particularly useful in the selection of transfected mammalian cells, yeast, and bacteria, and is widely employed in gene therapy, cloning, and cellular studies.

Gold Biotechnology Inc Carbenicillin Solution

Carbenicillin is a member of the penicillin -lactam antibiotics However unlike most -lactams carbenicillin disodium is limited to primarily gram-negative bacteria including Pseudomonas aeruginosa and common enteric species It can be used in selection protocols and is often preferred over ampicillin due to its increased stability This allows for less contamination of unwanted bacterial colonies In addition carbenicillin has been used to regulate bacterial growth in plants yielding low regeneration frequencies It can be used in genetic transformation applications to select for AmpR transformed cells
