Buffers

Resisting pH changes, buffers protect samples when acids or alkali is added. Powder and liquid forms efficiently track proteins during electrophoresis isolation and separation. The salty buffers can also be used to calibrate and standardize pH meters for accurate readings. Blocking substances stop antibody attachment to membrane free sites that would produce an interfering background. In various concentrations to fit any need, the buffers may come in liquids or dehydrated formats.

Supplier:  OMEGA BIOTEK
Description:   RNA Wash Buffer I
Supplier:  APPLICHEM LIFESCIENCE
Description:   Cloning Buffer, EDTA buffer solution pH 8,0 (0,5 mol/l)
Supplier:  APPLICHEM LIFESCIENCE
Description:   10X concentrated solution of 0,89 M Tris, 0,89 M boric acid and 0,02 M EDTA.Naâ‚‚, pH 8,3 ±0,2.
Catalog Number: (A7099.0125)

Supplier:  APPLICHEM LIFESCIENCE
Description:   Blocking Buffer I is based on a low-molecular weight, highly purified casein with NaCl and Tween® and stabilised with 0,1% ProClin® 300. It does not contain glycosylated proteins. Blocking Buffer I saturates free binding capacities on plastic consumables and other surfaces like ELISA plates and blotting membranes. Thus a reduction of unspecific binding on surfaces can be achieved. Efficiency of blocking is significantly improved in comparison to standard blocking procedures by a special production method, which leads to casein molecules with many different molecular sizes. Blocking Buffer I can be used in ELISA, EIA, RIA, Western blotting, immuno-PCR, protein arrays as well as immunohistochemistry.
UOM:  1 * 125 mL
Catalog Number: (A9162.0100)

Supplier:  APPLICHEM LIFESCIENCE
Description:   Tablets for preparation of 100 ml phosphate buffered saline (PBS).
UOM:  1 * 100 items
Supplier:  BIOWEST
Description:   These irrigating buffers and salt solutions are sterile, physiological balanced solutions intended for use in the maintenance of mammalian cells, where a chemically defined, balanced salt solution provides an environment that will maintain the structural and physiological integrity of cells <i>in vitro</i>. Applications include the intermediate steps for cultivation of cells, like washing, centrifugation, suspending and counting, as well as for many analytical methods or biochemical treatments. Principally these solutions should be used to keep the cells in suspension only for minutes or a few hours maximum. These buffers and solutions are not cell culture media.
Supplier:  OMEGA BIOTEK
Description:   The E.Z.N.A.® RNALock Stabilizer Reagent is an innovative reagent which rapidly lyses cells and tissues to inactivate RNases at room temperature. Simply submerge the samples, such as cell cultures, animal tissues, or white blood cells into the RNALock Stabilizer Reagent. The intact cellular RNA will be preserved even at elevated temperature. Samples can be stored in this reagent in excess of 12 months at −20 °C.
