Description

Bialaphos sodium is a freely soluble herbicide synthesized by Streptomyces hygroscopicus and Streptomyces viridochromeogenes.  It is commonly used for gene selection in cereals.

This product is considered a dangerous good. Quantities above 1 g may be subject to additional shipping fees. Please contact us for specific questions.

    CAS Number

    71048-99-2

    Molecular Formula

    C11H21N3NaO6P

    Molecular Weight

    345.27

    Mechanism of Action

    Bialaphos acts as a prodrug by separating into individual subunits of alanylalanine and phosphinothricin. Phosphinothricin is toxic to cells by triggering the accumulation of ammonia, and inhibiting photosynthesis and glutamine synthesis.

    Storage Conditions

    2-8°C

    Tariff Code

    2941.90.5000

Applications

    Microbiology Applications

    BIalaphos Sodium from TOKU-E was used to study its effects on oligopeptide transporters in a Sinorhizobium meliloti hfq mutant. (Sobrero et al, 2011)

    Plant Biology Applications

    Bialaphos Sodium is used in transformation of cereals including wheat, rice, maize, barley, sorghum, oat and rye. The bar gene is incorporated in the plant genome along with the gene of interest. When Bialaphos is applied, only plants which are successfully transformed survive (Aragão, 2002).
