ISOREAG,专注于稳定同位素,可提供多种2H、13C、15N、17O以及18O标记的氨基酸,所涉及到的氨基酸包括异亮氨酸(Isoleucine Ile)、亮氨酸(Leucine Leu)、赖氨酸(Lysine Lys)、蛋氨酸(Methionine Met又称甲硫氨酸)、苏氨酸(Threonine Thr)、色氨酸(Tryptophan Trp)、缬氨酸(Valine Val)和苯丙氨酸八种必需氨基酸,以及丙氨酸(Alanine Ala)、精氨酸(Arginine Arg)、门冬酰胺(Asparagines Asn)、门冬氨酸(Aspartic acid Asp)、半胱氨酸(Cysteine Cys)、谷氨酰胺(Glutamine Gln)、谷氨酸(Glutamic Glu)、甘氨酸(Glycine Gly)、组氨酸(Histidine His)脯氨酸(Proline Pro)、丝氨酸(Serine Ser)、酪氨酸(Tyrosine Tyr)等标准氨基酸。
氨基酸:含有氨基和羧基的一类有机化合物的通称,是含有碱性氨基和酸性羧基的有机化合物(非极性,酸性,碱性氨基酸),其中氨基连在α-碳上的为α-氨基酸。氨基酸包括L型和D型,其中组成蛋白质分子的氨基酸都是L-氨基酸。由于它们在同一pH环境中,各类氨基酸的带电状态不同,即它们具有不同的等电点(PI),这是电泳法和色谱法分离氨基酸的原理。
上海甄准生物可提供多种同位素标记的半胱氨酸,包括:L-半胱氨酸/ DL-半胱氨酸;N-乙酰基-S-苯基-DL-半胱氨酸/ N-乙酰基-S-苯甲基-DL-半胱氨酸;L-半胱氨酸微生物/热原试验等。
如需更多稳定同位素标记的其它氨基酸,请联系上海甄准生物,具体稳定同位素标记的半胱氨酸产品信息如下:
