Research Products International Corp Chloramphenicol, 25 Grams

Chloramphenicol is a phenicol-class antibiotic effective against a broad range of Gram-positive and Gram-negative bacteria. Commonly used in microbiology, cell culture, molecular biology, and genetic engineering, it serves as a selective agent by inhibiting bacterial protein synthesis via the 50S ribosomal subunit. It allows the growth of cells carrying the Chloramphenicol resistance gene while inhibiting non-transformed cells. It is used to maintain plasmids and vectors with the resistance gene and supports studies on gene expression and protein synthesis.

Research Products International Corp Kanamycin Monosulfate [Kanamycin A], 5 Grams

Kanamycin A is a broad-spectrum aminoglycoside antibiotic derived from Streptomyces kanamyceticus. It is widely used in microbiology, molecular biology, and genetic engineering as a selective agent. Commonly added to culture media, Kanamycin A inhibits the growth of non-resistant bacteria, allowing selection of cells carrying a kanamycin resistance gene. It is frequently used in recombinant DNA experiments and as a selectable marker in plasmids and other vectors. Researchers also use it to study bacterial resistance and antimicrobial efficacy. Its potency and low toxicity make it valuable in protein expression and genetic studies.

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.

Electron Microscopy Sciences Pronase Reagent Ready To Use 100 ML

Pronase is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In IHC most commonly used fixative like formalin mask tissue antigens (cellular, membrane and nuclear) by cross-linking process, this results in poor or no staining in IHC. Pronase digestion of FFPE tissue section improves accessibility of antibodies to tissue antigens.

Store in temperature of 2-8 degree C. DO NOT FREEZE.

Intented Use: Use as antigen retriever for some antibodies in IHC. Please refer to primary antibody protocol for IHC.
