Thioglycollate Broth Usp Alternative
Login to see pricesBrand:
Thermo ScientificTM OxoidTM
Thioglycollate Medium USP – Alternative, is intended for sterility testing with certain biological products that are turbid or otherwise do not lend themselves readily to culturing in Thioglycollate Medium USP (CM0173) because of its viscosity.
Thioglycollate Medium USP – Alternative, Oxoid Composition
| Typical Formula* | gm/litre |
| L-cystine | 0.5 |
| Sodium chloride | 2.5 |
| Glucose | 5.5 |
| Yeast extract | 5.0 |
| Pancreatic digest of casein | 15.0 |
| Sodium thioglycollate | 0.5 |
| pH 7.1 ± 0.2 @ 25°C |
Thioglycollate Medium USP – Alternative, Oxoid Preparation:
Suspend 29g in 1 litre of distilled water. Bring to the boil and dissolve the medium completely. Distribute into tubes or bottles and sterilise by autoclaving at 121°C for 15 minutes.
PREPARE FRESHLY OR BOIL AND COOL THE MEDIUM JUST BEFORE USE.
Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Whilst storage of the prepared medium is not recommended, autoclaved volumes of Thioglycollate Medium USP – Alternative, should be held at 20-30°C in the dark. Storage at lower temperatures increases oxygen absorption.
Precautions
This medium lacks agar and reducing indicator, therefore it is essential that the medium is freshly prepared and used within four hours of preparation.
Thioglycollate media should not be reheated more than once because toxic oxygen radicles are formed on reheating.

Thioglycollate Medium (USP) (Dehydrated), Oxoid Preparation:
Suspend 29.75 g in 1 litre of distilled water. Bring to the boil to dissolve completely. Distribute into final containers, sterilise by autoclaving at 121°C for 15 minutes. Mix well and cool to room temperature.
Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared medium away from light at room temperature.
Precautions
If the upper portion of the medium is red because of oxidation, anaerobic conditions can be restored by reheating for 10 minutes in boiling water or steam. Do not reheat more than once.
Following reheating, if more than one-third of the medium is oxidised then it should be discarded.
Some glucose-fermenting organisms which are able to reduce the pH of the medium to a critical level may not survive in this medium. Early subculture is necessary to isolate these organisms.

Suspend 20g in 1 litre of distilled water. Bring to the boil, mix well and allow to stand until completely dissolved. Distribute into final containers and sterilise by autoclaving at 121°C for 15 minutes.
Media containing small quantities of agar are liable to separate if cooled rapidly. Tubes of reconstituted and autoclaved medium should be allowed to cool slowly on a wooden surface in a draught-free atmosphere.
Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
The prepared medium should be stored away from light at room temperature.
Precautions
Check the upper portion of the prepared medium before inoculation. If more than one-third of the fluid is oxidised i.e. green coloured, discard the bottle.
If one-third or less fluid is oxidised, then heat in boiling water with the cap loosened to drive off oxygen. Cool to room temperature before inoculation. This reheating process can only be carried out once because of the formation of toxic radicles in the medium.
Organisms which ferment glucose and lower the pH to critical levels may not survive in this medium after growth has taken place.

Merck
Description
CAS number: 108-88-3
Chemical Formula: C₆H₅CH₃
Molar Mass: 92.14 g/mol
Synonyms: Toluol, Methylbenzene
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved. Filtered by 0.2 µm filter.

Sigma
Description:
Synonyms : DNA/RNA/protein extraction reagent, DNA/RNA/protein isolation reagent, DNA/RNA/protein purification reagent, TRI Reagent® cell pellet solution, cell pellet RNA extraction, cell pellet RNA isolation, cell pellet RNA purification, single step RNA extraction reagent, single step RNA isolation reagent, single step RNA purification reagent, total RNA extraction solution, total RNA isolation solution, total RNA purification solution, TRI Reagent® RNA Isolation Reagent.
TRI reagent® is a quick and convenient ready-to-use reagent useful for efficient total RNA extraction or for the simultaneous isolation of RNA, DNA and protein. TRI reagent® is a mixture of guanidine thiocyanate and phenol in a monophasic solution.
Homogenization or lysis of the tissue sample in TRI reagent® dissolves RNA, DNA and protein. The addition of chloroform or 1-bromo-3-chloropropane followed by centrifugation results in the separation of the mixture into three phases: an aqueous phase containing the RNA, the interphase containing DNA, and an organic phase containing proteins. Each of the components can then be isolated after separating the phases.
