Gold Biotechnology Inc L-Arabinose 250 g
L-Arabinose is an arabinose isomer widely found in nature, while D-arabinose is less common. L-Arabinose is a constituent of many biopolymers that make up plant cell walls.
Gold Biotechnology Inc Carbenicillin (Disodium), USP Grade 25 g
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.
Gold Biotechnology Inc Proteinase K, RNase/DNase free 100 mg
Proteinase K is a highly reactive nonspecific serine protease that belongs to the subtilisin family of proteins. It cleaves at the carboxylic acid side of aliphatic, aromatic, or hydrophobic amino acids. Proteinase K is capable of inactivating RNases and DNases and is used in the isolation or preparation of high molecular weight nucleic acids. Proteinase K is also useful for helping to characterize enzymes, due to its cleavage specificity. This enzyme was designated proteinase K because of its ability to hydrolyze keratin. Proteinase K is stable in a wide variety of detergents and buffer salts and at various temperatures and pH. The isoelectric point of proteinase K is 8.9.
Gold Biotechnology Inc Carbenicillin (Disodium), USP Grade 5 g
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.
Gold Biotechnology Inc 5-Fluoroorotic acid monohydrate (5-FOA) 5 g
5-Fluoroorotic Acid (5-FOA) is widely used in the field of yeast molecular genetics. The toxicity of 5-FOA to yeast cells with a functioning URA3 gene which encodes orotidine-5′-P decarboxylase (OMP decarboxylase), makes it especially useful for the selection and identification of mutant yeast strains. 5-FOA is most often applied with Saccharomyces cerevisiae (URA3), although it has been used in other strains including Schizosaccharomyces pombe (URA4 and URA5), Candida albicans (URA3) and the bacterium E. coli (pyrF). The use of 5-FOA in the yeast 2-hybrid system allows for the construction of activation domain hybrid libraries to identify protein-protein interactions.
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.
Gold Biotechnology Inc IPTG 50 g
IPTG is an analog of galactose that is non-metabolizable and inactivates the lac repressor to induce synthesis of β-galactosidase in E. coli. The expression of cloned genes under the control of the lac operon is induced by IPTG. It is also a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria.
Gold Biotechnology Inc MUG 1 g
4-Methylumbelliferyl beta-D-glucuronide (MUG) is a fluorogenic substrate for beta-glucuronidase (GUS). Upon cleavage, MUG yields blue fluorescence seen under UV light.
Gold Biotechnology Inc Kanamycin Monosulfate, USP Grade 100 g
Kanamycin is an aminoglycoside antibiotic isolated from Streptomyces kanamyceticus. It is effective against gram-positive and gram-negative bacteria as well as Mycoplasma species. Kanamycin is commonly used to select for bacteria that have been transformed with a kanamycin-resistant gene and plant tissues that have the NPT II (APH3) gene incorporated in them. Kanamycin is very soluble in aqueous solution and is typically used in concentrations of 50-100 µg/ml.
Gold Biotechnology Inc Nourseothricin Sulfate (Streptothricin Sulfate) (NTC or clonNAT) 100 mg
Nourseothricin is a broad-spectrum antibiotic derived from Streptomyces noursei. In addition to being effective on prokaryotic cells of gram-positive and gram-negative bacteria, various fungi including Candida albicans, and certain DNA and RNA viruses, it is also effective on eukaryotic cells of higher eukaryotes. It has been used as a selection agent for cells containing the gene conferring resistance to it.
Gold Biotechnology Inc Spectinomycin Dihydrochloride Pentahydrate, USP Grade 5 g
Spectinomycin is an aminocyclitol antibiotic isolated from Streptomyces spectabilis. It is effective against gram-positive and gram-negative bacteria, but most commonly used against Gonococcus species. It has also been used to monitor cell fate during leaf development and as a selection marker in plants to display successful transformation of the Spcr gene.
Gold Biotechnology Inc Blasticidin S HCl 25 mg
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.
