Aldehyde Reagents (pALD, bALD)

 * Laysan Bio is pleased to introduce a new product line, the Butyraldehyde-PEG-Valeric Acid (bALD-PEG-VA).  This reagent is a new catalog item in the 3400 molecular weight but may be made in the 2,000, 5,000, 10K, and 20K molecular weights as custom items.  The bALD-PEG-VA line offers the ability to react the Butyraldehyde functional group with a primary amine of one molecule and then perform a direct condensation between the valeric acid functional group and a primary amine of a second molecule.  This two-step process allows the intermediate conjugate to be purified before the second reaction step resulting in a more pure final product.
