Phosphate-buffered saline (PBS) is a balanced salt solution that is used for a variety of cell culture applications, such as washing cells before dissociation, transporting cells or tissue samples, diluting cells for counting, and preparing reagents. PBS is formulated without calcium and magnesium for rinsing chelators from the culture before cell dissociation.

Phosphate-buffered saline (PBS) is a balanced salt solution that is used for a variety of cell culture applications, such as washing cells before dissociation, transporting cells or tissue samples, diluting cells for counting, and preparing reagents. PBS is formulated without calcium and magnesium for rinsing chelators from the culture before cell dissociation.
Application
A concentrated, standard phosphate buffer solution.
pH Range: 7.3 - 7.5
Recommended Storage Condition: Room temperature
The β-galactosidase substrate X-Gal (5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside) is a chromogenic stain for β-gal activity, and is commonly used to distinguish between recombinants and nonrecombinants by lacZ α-complementation with appropriate vectors and hosts.
D-(+)-Glucose is a common natural sugar involved in processes such as energy production, glycosylation, and formation of glycans that provide structure to cells. Glucose is involved in a detrimental process in cells called glycation. Glucose is used as a supplement for cell culture and in numerous cellular processes and molecular biology applications.
Kanamycin Sulfate solution is an aminoglycoside antibiotic consisting of a six-membered aminocyclitol ring attached to aminosugar side chains through glycosidic bonds. Kanamycin Sulfate solution acts by inhibiting protein synthesis, and compromising translational fidelity in susceptible bacteria.
The Super-DITM Formamide is the recommended sample loading buffer for all ABI sequencers.
Tris Buffered Saline (TBS) is an isotonic, non-toxic buffer used in some biomedical techniques to maintain pH within a relatively narrow range. TBS can shift pH relatively drastically as temperature changes, with the pKa declining approximately 0.03 units per degree Celsius rise in temperature.
Ammonium Persulfate (APS) is an oxidizing agent that is used with TEMED to catalyze the polymerization of acrylamide and bisacrylamide to prepare polyacrylamide gels for electrophoresis.
MCLAB's high-purity 30% acrylamide/bis-acrylamide solution is a safer alternative to handling powdered acrylamide.
Bovine Serum Albumin (BSA) has many uses as a carrier protein and as a stabilizing agent in enzymatic reactions. MCLAB’s Ultrapure BSA is a "non-acetylated" BSA, pure enough to use when the integrity of DNA or RNA is essential. It has been tested for DNase, RNase, endonuclease, protease, peroxidase, and alkaline phosphatase activity, and assayed for fluorescence background.
IPTG (isopropyl-beta-D-thiogalactopyranoside) is a highly stable synthetic analog of lactose. It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under the control of the lac operon.
A routine use of agarose is ideal for daily analysis of nucleic acids by gel electrophoresis or blotting (Northern or Southern) and is also suitable for protein applications such as Ouchterlony and radial immunodiffusion (RID). It has low ethidium bromide and SYBR Green background staining.
Buffer EB is the elution buffer used in many Qiagen kits, e.g. PCR, Gel Extraction, Nucleotide Removal Kits, MinElute Kits and the QIAprep Miniprep Kits for DNA cleanup or small-scale plasmid purification. The purified DNA can also be eluted in TE (10 mM Tris-Cl, 1 mM EDTA, pH 8.0), but the EDTA may inhibit certain subsequent enzymatic reactions.
