Yeast Extract Powder Bacto For E. Coli Bacterial Culture, Petri Dish LB Plate Preparation, 500 Grams/Bottle

Yeast extract Powder is the water-soluble portion of autolyzed yeast, often used in bacterial culture media in liquid and solid versions. Yeast extract contains a mixture of amino acids, peptides, water soluble vitamins and carbohydrates which are great for bacterial optimal growth. One bottle of 500 grams of yeast extract for only $68.00. Free shipping on orders of $200. Lowest price on the market guaranteed! We match the prices from our competitors in US market.

When you grow bacterial E. Coli for protein isolation, purification, plasmid DNA preparation or direct colony screening for PCR, you don’t want your bacteria have too much carbohydrates which normally leads to difficulties of protein purification, low yield and poor purity of plasmid DNA, and inhibition of PCR application during direct colony screening. One way researchers do is to avoid bacterial overgrowth which generates too much carbohydrates. Another way is to reduce the raw material used to build bacterial cell walls.

Our manufacturer focuses on optimization of bacterial cell growth and slightly removes some raw nutrient materials, which helps researchers achieve high pure protein, plasmid DNA and better PCR results. At the same time certain amount of pigments in the yeast extract powder were also removed, which gives better microscope background when researchers study morphology of bacteria. Removal of certain compounds in the yeast extract does not affect bacterial growth. Please try our product. If you are not satisfied your money will be 100% refunded.
