Antibiotics

Gold Biotechnology offers more than 150 unique antibiotic agents for use in a wide variety of cell culture, microbiology and molecular biology applications. Antibiotic agents are often clinically used to inhibit bacterial growth or kill bacteria as selection markers in agar or liquid media. The first commercially available antibiotics were developed in the 1930s, starting with the sulfonamides in 1932 and exploded later with the discovery of penicillin in 1942. Gold Biotechnology’s antibiotics cover 14 classes, including aminoglycosides, carbapenems, macrolides, penicillins, quinolones, sulfonamides and tetracyclines, as well as multiple generations of cephalosporin antibiotics.

Description

Blasticidin S is an aminoacylnucleoside antibiotic isolated from Streptomyces griseochromogenes. It shows high efficacy against both eukaryotic and prokaryotic cells. Aside from its antimicrobial properties, blasticidin has displayed antiviral, antitumor, and antifungal properties and has been used as a selection agent. It has been used to select for cells containing the bls, bsr, or BSD resistance gene as well as HEK293-T cells and HEK-D5 cells. Additionally, blasticidin is effective in preventing cell culture contamination and studying protein synthesis.

Bleomycin A5 hydrochloride

B-405-10 10 mg $ 179.00
B-405-50 50 mg $ 415.00

Description

Bleomycin A5 hydrochloride is a compound part of the glycopeptide antibiotic family. It is currently used in oncology research for its strong stimulatory and inhibitory effects. Bleomycin A5 greatly reduces telomerase activity, hindering the proliferation of malignant cells. It has also been shown to induce in vivo fibrosis and inflammation by generating peroxynitrites, a strong oxidizing agent.

Bleomycin A5 stimulates downstream apoptosis by increasing cysteine-aspartic acid protease-3 (caspase-3) activity, tumor protein 53 (p53) production and transforming growth factor beta 1 (TGF-beta 1) formation. These proteins induce apoptosis directly or indirectly by halting cell growth.

Bleomycin Sulfate, USP Grade

B-910-10 10 mg $ 122.00
B-910-50 50 mg $ 423.00

Description

Bleomycin Sulfate is an anti-cancer agent isolated from Streptomyces verticillus. Bleomycin is a mixture of bleomycin A2 and bleomycin B2, in an approximately 2:1 ratio, respectively. However, the ratio varies by lot number.

Bleomycin is used against Hodgkin’s lymphoma. Its mechanism is not well understood; however, it is though that bleomycin chelates metallic ions causing a decrease in enzyme stability. The enzymes react with oxygen and produce free radicals, ultimately causing single-stranded breaks in deoxyribose sugars of DNA.

Description

Brefeldin A is an antibiotic derived from Penicillium brefeldianum. It is an anti-cancer agent which disrupts protein transport and causes apoptosis of tumor cells. Brefeldin A disrupts the function of the Golgi apparatus and blocks Golgi-COPI activity. ER vesicles are prevented from fusion with the Golgi and are secretion is inhibited. Additionally, Brefeldin A is an ARF inhibitor, sphingomyelin cycle activator, and caspase-3 activator. It has been shown to induce apoptosis in leukemia cells and colon cancer cells.

Description

Carbenicillin is a member of the penicillin β-lactam antibiotics. However, unlike most β-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.
