pH-Indicator Strips, MQuant® (Merck)

Brand:

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.

RPMI-1640 Medium-Sigma Aldrich

Brand:

Sigma

Description

pH : > 7.2

Components :

HEPES: 20 mM
NaHCO3: no
sodium pyruvate: no
phenol red: yes
L-glutamine: yes

RPMI 1640 Medium was developed at Roswell Park Memorial Institute in 1966 by Moore and his co-workers. A modification of McCoy′s 5A Medium, it was formulated to support lymphoblastoid cells in suspension culture, but it has since been shown to support a wide variety of cells that are anchorage-dependent. Originally intended to be used with a serum supplement, RPMI 1640 has been shown to support several cell lines in the absence of serum. It has also been widely used in fusion protocols and in the growth of hybrid cells. This medium is suitable for culturing human normal and neoplastic leukocytes.

RPMI-1640 medium formulation is based on the RPMI-1630 series of media utilizing a bicarbonate buffering system and alterations in the amounts of amino acids and vitamins. It is used for the culture of human normal and neoplastic leukocytes. RPMI-1640 also supports the growth of various types of cell cultures, like fresh human lymphocytes in the 72-hour phytohemagglutinin (PHA) stimulation assay.
