Sisomicin is a broad-spectrum aminoglycoside antibiotic isolated from Micromonospora inyoensis. It is related to gentamicin and targets gram-negative and gram-positive bacteria such as Klebsiella species, E. coli, P. aeruginosa, Enterobacter species, and Proteus species. It has been used in disk and tube dilution sensitivity assays.

2,4-Dihydroxybenzoic acid is a resorcylic acid with a large number of applications. It possesses antioxidant, anti-radical and hydrogen peroxide scavenging. It also has potential as a wastewater treatment when activated with ultrasound. As a reagent it has been used to synthesize mycophenolic acid, protein 90 inhibitors and pde4 inhibitors.

Sodium polyanetholesulfonate (SPS) is a homopolymer that was developed to be used as an anticoagulant. It is commonly used in blood culture media for bacteria because it inhibits the antimicrobial activity of immune system components present in blood. SPS inhibits the growth of some microorganisms, but this effect if often media-dependent and can be overcome by addition of gelatin or lysed blood. SPS is a weaker anticoagulant than heparin, most likely due to inhibition of antithrombin III, but a stronger inducer of platelet aggregation. It has also been used to stabilize colloidal suspensions.

DL-3-Tyrosine has a hypotensive effect on blood pressure and is converted to dopamine in rats. It can also be used as a reagent for chemical synthesis.

Tropine is a derivative of tropane, which contains a hydroxyl group. It a a building block for the synthesis of atropine, an anticholinergic drug.

Fraxetin is a phenolic antioxidant. It has been used to protect against rotenone-induced apoptosis in neuroblastoma cells. Fraxetin also possesses antitumor and antimetastatic properties on M2 macrophage differentiation.

When it comes to labeling your samples, reliability is really important!

That's why GoldBio’s permanent markers are Sharpie brand, meaning you get the consistency and dependability you’ve come to know and love from both of your favorite brands.

Salinomycin is a coccidiostat ionophore antibiotic isolated from Streptomyces albus. It increases cation movement across cell membranes through exchange-diffusion, resulting in altered gradients due to a lack of control of ion permeability. This effect allows ions (K+, Na+, Ca+, Mg2+) to accumulate inside the cell, reaching toxic levels.
