For Specialized Amino Acid文和 Applications with Po醫笑stcolumn Derivati來國zation

The AminoPac^® PA1 column is a high-speed, pellic司和ular, strong, anion-exchange column. Th制多e PA1 delivers high-efficiency s刀子eparations as a result of 女呢its nonporous-core particle.雨劇 Its strong anion-e道少xchange characteristics are imparte票會d by agglomerating 司玩surface MicroBead™ 草他particles that are functionalized黑吧 with the quaternary ammonium fun要件ctional group, resulting in a hi可道gher capacity than typically offe黑分red by nonporous resins.

• Resolves phosphorylated and other am那舊ino acids by anion-exchange chromatogra服為phy

• Separates acid-亮答labile amino acids under basic p身拿H conditions

• Separates strong空愛ly acidic amino acids

• Requires OPA or ninhydrin postcolu在妹mn derivatization

The anion-exchange 中喝selectivity of the Ami費對noPac PA1 can be used to re和頻solve peaks that c裡暗annot be resolved using a cat相媽ion-exchange column. Fo能窗r example, O-phospho外校rylated amino acids are resolved an土書d eluted near the end of a hydr放靜olysate chromat道通ogram. Arogenic acid, a precursor to t很他yrosine and phenylalanine, decomposes 水快under the acidic cond男拍itions required for cation-exchange s林房eparation or PITC derivati林風zation, but it is stable in文懂 alkaline eluent間做s used with AminoPac PA1 column.

The PA1 is particularly well suited 問很for acidic and acid-lab還森ile amino acids and for amino a爸笑cid pairs not completely r都訊esolved by cation-ex都計change chromatography.
