How to use Ornithin Decarboxlase Medium

Ornithin Decarboxlase Medium presents in all nucleated cells and is the rate-limiting enzyme for synthesis of polyamines.It is used for the cultivation and differentiation of bacteria based on their ability to decarboxylate the amino acid. Bacteria that decaboxylate ornithine turn  the medium turbid purple.

Ornithin Decarboxlase Medium is nice Biochemical medium.

Usages:

Ornithin Decarboxlase Medium is used for the identification of intestinal species with the ability to produce amino acid decarboxylase.

Original rationale:

Peptone and yeast extract powder to provide nitrogen, vitamins and growth factors; glucose to fermentable sugars; bromocresol purple as pH indicator, acid yellow, purple alkaline; in basic medium by adding lysine, arginine acid and ornithine test whether the bacteria produce the enzyme than the substrate.

MacConkey agar for your choice

MacConkey agar is a culture medium designed to grow Gram-negative bacteria and stain them for lactose fermentation. Acting as a visual pH indicator, the agar distinguishes those Gram-negative bacteria that can ferment the sugar lactose (Lac+) from those that cannot (Lac-).
MacConkey agar is used for isolation and culture of enteric pathogens and non-fermenting bacteria identification.
[Preparation Method]
Peptone 20g, NaCl 5g, bile salts (pigs, cattle, sheep) 5g, lactose 10g, agar 15 ~ 20g, 1% neutral red solution, 5ml, distilled water 1L.

The function of Taq DNA Polymerase

Taq DNA Polymerase is a highly thermostable DNA polymerase of the thermophilic bacterium Thermus aquaticus. The enzyme catalyzes 5'=>3' synthesis of DNA, has no detectable 3'=>5' exonuclease (proofreading) activity and possesses low 5'=>3' exonuclease activity. In addition, Taq DNA Polymerase exhibits deoxynucleotidyl transferase activity, which frequently results in the addition of extra adenines at the 3'-end of PCR products. Recombinant Taq DNA Polymerase is ideal for standard PCR of templates 5 kb or shorter.
Taq DNA polymerase (recombinant) is cell with a cloned pol gene from Thermus aquaticus YT1.

What is Ornithin Decarboxlase Medium

Ornithin Decarboxlase Medium By binding the virus or toxin-specific , and directly play the effect on the virus.

Antibody function:

The primary function of Ornithin Decarboxlase Medium  is antibodies and antigens (including foreign and their own) combine to effectively clear the microorganisms invade the body, parasites and other foreign matter, antibodies (antibody) response is an antigen produced, with antigen-specific binding proteins. Each with a specific antibody binding epitopes. This combination can make the antigen inactivation, may also be ineffective but sometimes cause pathological damage to the body, such as anti-nuclear antibody, anti-double-stranded DNA antibodies, anti-thyroglobulin antibodies and some other autoantibodies, can cause the human body hazards.

Initially it was proved by electrophoresis of serum antibody activity in the γ-globulin in part, so once antibody referred to as gamma (γ) globulin. It was discovered that not all antibodies in the γ region; and in the area of γ-globulin necessarily had antibody activity.
