Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared medium at 2-8°C.
Precautions
Black colonies appearing on these two media may be organisms other than Clostridium perfringens.

pH-Indicator Strips, MQuant® (Merck)
Login to see pricesBrand:
Merck
Description
The MQuant® pH tests are suited for all media in environmental analysis and in industrial in-process controls. Our special method of manufacture gives the pH indicator strips decisive advantages over the indicator paper: since the indicator does not bleed, the strip can be left in the measurement medium without contaminating it. Using these test strips is fairly easy, the pH value is measured semiquantitatively by visual comparison of the reaction zone on the test strip with the fields of the color scale, perfectly matching the reaction color. The clever Safetyedge boxes allow for safe storage and convenient withdrawal of the test strips. For tests for other parameters that require a specific pH range of the sample (e.g. Spectroquant®, see instructions of use), we recommend the use of MQuant® pH test strips as pre-test.

General description
Phorbol 12-myristate 13-acetate is a phorbol ester. It works as a tumour promoter and is involved in gene transcription, cell growth, differentiation, programmed cell death, immune pathway and receptor desensitization via protein kinase C (PKC) signalling pathways. Phorbol 12-myristate 13-acetate is also a model agent to study growth factors-, hormones-, and cytokines-mediated regulation of cellular growth and differentiation.
Application
Phorbol 12-myristate 13-acetate has been used for the stimulation of various cells including spleen cells, quiescent lymphocytes and fetal thymocytes. It has also been used for the activation of PKC (protein kinase C) in cells.
Solubility
DMSO: soluble (Dissolve in water-miscible organic solvent prior to preparing aqueous solutions. DMSO solutions can be stored dark at -20 °C for at least six months.)

Sigma
Description
CAS Number : 24867-26-3
Phosphate-buffered saline (PBS) is a buffer solution used in biological research. It is a water-based salt solution containing sodium phosphate, sodium chloride and, in some formulations, it contains potassium chloride and potassium phosphate. The osmolality and ion concentrations of the solutions match those of the human body (isotonic) and are non-toxic to most cells.
Application :
- For the production of platinum nanoparticles (NP-Pt) hydrocolloids
- For the washing of blood sample and SEM (scanning electron microscope) stubs prior to SEM
- For preparing the solution of fluorescent lectin wheat germ agglutinin (WGA)
- For the dilution of capture antibody during ELISA (enzyme linked immunosorbent assay)
- For suspension of cell pellets during centrifugation
- In immunoassay procedures.
One tablet dissolved in 200 mL of deionized water yields 0.01 M phosphate buffer, 0.0027 M potassium chloride and 0.137 M sodium chloride, pH 7.4, at 25 °C.
