    HazMat Fee

    An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

    The shipment is processed through FedEx Ground under the Limited Quantity option.

    Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

    If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

Zein is a prolamine and an alcohol soluble protein present in maize endosperm cells. Zein is a 20kDa structural protein and is encoded by the gene mapped on the short arm of maize chromosome 7. This protein lacks essential amino acids, such as lysine and tryptophan. Therefore, it has a poor nutritional value.Zein has been used as a biopolymer in electrospinning technique. It has also been used to blend starch involved in the manufacture of thermoplastic material.

Application

H₂N-PEG₂-CH₂COOH serves as a versatile bifunctional linker for conjugation and polymer synthesis, combining the stability of a short PEG spacer with amine and carboxylic acid termini. The primary amine enables efficient coupling to activated esters or aldehydes, while the terminal carboxylic acid facilitates amide bond formation or further derivatization. Its balanced solubility and robustness under standard reaction conditions make it ideal for peptide modification, bioconjugation, and the construction of functionalized polymers in medicinal chemistry workflows.
