标准物质的特性分为五大类：

1、化学成分类：标准物质，纯的化合物或是有代表性的基体样品，天然的或添加(被)分析物的(如，用作农药残留分析的添加了杀虫剂的动物脂肪)，以一种或多种化学或物理化学特性值表征。

2、生物和临床特性类：与目录A相似的标准物质，但以一种或多种生化或临床特性值表征，如酶活性。

3、物理特性类：以一种或多种物理特性值表征的标准物质，如熔点、粘性和密度。

4、工程特性类：以一种或多种工程特性值表征的标准物质，如硬度、拉伸强度和表面特性。

5、其他特性。这些类别又被细分为三级子类，例如，在化学成分类中，以微量锰、硅、铜、镍和铬含量表征的铝合金，列于化学成分一金属一有色金属一铝合金的子类中；在化学成分类别中，标准物质还可进一步被分为单一成分的标准物质和基体标准物质两大类；单一成分的标准物质是纯物质(元素或化合物)，或纯度、浓度、熔点、熔化焓值、粘度、紫外可见光吸光率、闪点等参考值已确定的纯物质的溶液；这类标准物质的重要用途之一是分析仪器 的检定或校准。

低密度脂蛋白抗体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.丝氨酸脱羧酶检测试剂盒
