SpikeMix™ Non-quantified PTM Reference KitsDespite recent improvements, PTM proteomics is still challenging. Typical problems are low endogenous abundance, low ionization intensity, changed fragmentation, limited stability during proteomics workflows, and/or complex fragmentation spectra interpretation, especially regarding correct PTM site localization. Our defined and carefully selected synthetic PTM reference peptides support PTM proteomics and help to overcome these challenges and are applicable for direct usage as reference material in mass-spectrometry based proteomics.
Available PTMs as peptide pools:Phospho(serine, threonine, tyrosine), Arg(Me, Me2a, Me2s), Lys(Ac, Me, Me2, Me3, Cro, Suc, Mal, Biotin, Glu, For, Prop, But, Hib, GG), Glyco-Thr(alphaDGalNAc), Glyco-Ser(alphaDGalNAc). The peptides are part of a collection of 30 x 100 peptides that comprises wild-type peptides as well as 24 different post-translational modifications (PTMs)
Benefits of SpikeMix™ Non-quantified PTM Reference Kits - Large range of PTM reference peptides - Selected for high recovery in LC-MS- 100 peptides in one pool

（1）优级纯试剂 亦称保证试剂，为一级品，纯度高，杂质极少，主要用于精密分析和科学研究，常以GR表示。
（2）分析纯试剂 亦称分析试剂，为二级品，纯度略低于优级纯，杂质含量略高于优级纯，适用于重要分析和一般性研究工作，常以AR表示。
（3）化学纯试剂 为三级品，纯度较分析纯差，但高于实验试剂，适用于工厂、学校一般性的分析工作，常以CP表示。
（4）实验试剂 为四级品，纯度比化学纯差，但比工业品纯度高，主要用于一般化学实验，不能用于分析工作，常以 LR表示。
以上按试剂纯度的分类法已在我国通用。根据化学工业部颁布的“化学试剂包装及标志”的规定，化学试剂的不同等级分别用各种不同的颜色来标志，见表1。
