The reaction of N-succinimidyl acetate with insulin was studied using different ratios of the reagent and protein and at various pH values; the most favorable condition was the use of 10: 1 ratio of the reagent: insulin, with incubation time of 10 min in 20 mM sodium borate
buffer, pH 12.
An example water solution consists of 69-81 wt% water, 1-20 wt% ammonium polyphosphate, 4-5 wt% sodium borate
, 4-5 wt% boric acid, and 0.
0 mL of L-phenylalanine (Sigma-Aldrich, EUA) (60 mm) in sodium borate
As many as ten mixtures were prepared for a standard curve and were made with desired aliquot volumes from the stock solution of riboflavin combined with sodium borate
, also known as borax, and boric acid are added to many products as cleaning agents, enzyme stabilizers or for other functions.
Borax, Boric acid, Sodium Borate
, Solubor, and Sodium tetra-borate can be used as boron fertilizers.
This might require writing more than one name, such as sodium borate
, borax or sodium tetraborate decahydrate.
Remove stains from Fabrics before washing by rubbing a paste of dishwasher detergent and sodium borate
into the fabric and rinsing.
For example, Espree Natural Aloe Optisoothe Eye Wash for Dogs & Cats contains purified water, aloe vera, benzalkonium chloride, and sodium chloride; V-Pro Eye Rinse for Dogs contains boric acid, purified water, sodium borate
, and sodium chloride; and the human product OcuFresh Eye Wash contains sodium chloride, sodium borate
, and boric acid.
Storage buffer solution 2 consisted of 10 mmol/L sodium borate
buffer (pH 7.
Sapwood blocks of white pine and American beech were impregnated in a two-step treatment with either a 5 percent copper chloride solution or a mixture of 5 percent copper chloride and 2 percent sodium borate
followed by impregnation with a phenol-formaldehyde resin containing various concentrations of a softwood-bark-derived pyrolytic oil.
