標準物質的特性分為五大類:
1、化學成分類:標準物質,純的化合物或是有代表性的基體樣品,天然的或添加(被)分析物的(如,用作農藥殘留分析的添加了殺蟲劑的動物脂肪),以一種或多種化學或物理化學特性值表征。
2、生物和臨床特性類:與目錄A相似的標準物質,但以一種或多種生化或臨床特性值表征,如酶活性。
3、物理特性類:以一種或多種物理特性值表征的標準物質,如熔點、粘性和密度。
4、工程特性類:以一種或多種工程特性值表征的標準物質,如硬度、拉伸強度和表面特性。
5、其他特性。這些類別又被細分為三級子類,例如,在化學成分類中,以微量錳、硅、銅、鎳和鉻含量表征的鋁合金,列于化學成分一金屬一有色金屬一鋁合金的子類中;在化學成分類別中,標準物質還可進一步被分為單一成分的標準物質和基體標準物質兩大類;單一成分的標準物質是純物質(元素或化合物),或純度、濃度、熔點、熔化焓值、粘度、紫外可見光吸光率、閃點等參考值已確定的純物質的溶液;這類標準物質的重要用途之一是分析儀器 的檢定或校準。

低密度脂蛋白抗體Function : Plays a central role during spermatogenesis by repressing transposable elements and prevent their mobilization, which is essential for the germline integrity. Plays an essential role in meiotic differentiation of spermatocytes, germ cell differentiation and in self-renewal of spermatogonial stem cells. Its presence in oocytes suggests that it may participate in similar functions during oogenesis in females. Acts via the piRNA metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and govern the methylation and subsequent repression of transposons. Directly binds piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a Dicer-independent mechanism and are primarily derived from transposons and other repeated sequence elements. Associates with primary piRNAs in the cytoplasm and is required for PIWIL4/MIWI2 nuclear localization and association with secondary piRNAs antisense. The piRNA process acts upstream of known mediators of DNA methylation. Participates in a piRNA amplification loop. Besides their function in transposable elements repression, piRNAs are probably involved in other processes during meiosis such as translation regulation. Indirectly modulate expression of genes such as PDGFRB, SLC2A1, ITGA6, GJA7, THY1, CD9 and STRA8. Inhibits tumor cell growth when repressed. When overexpressed, acts as an oncogene by inhibition of apoptosis and promotion of proliferation in tumors.絲氨酸脫羧酶檢測試劑盒
