26S Proteasome Regulatory Subunit 6A (PSMC3) Blocking Peptide is a blocking peptide which can be used to block the reactivity of the abx133494 PSMC3 Antibody. The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. The 19S regulator is composed of a base, which contains 6 ATPase subunits and 2 non-ATPase subunits, and a lid, which contains up to 10 non-ATPase subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes one of the ATPase subunits, a member of the triple-A family of ATPases that have chaperone-like activity. This subunit may compete with PSMC2 for binding to the HIV tat protein to regulate the interaction between the viral protein and the transcription complex. A pseudogene has been identified on chromosome 9.

Isotype Control 同型对照 同型对照（Isotype Control），使用与一抗相同种属来源、相同亚型、相同剂量和相同的免疫球蛋白及亚型的免疫球蛋白，用于消除由于抗体非特异性结合到细胞表面而产生的背景染色。 同型对照 同型对照的主要目的是确定一抗的结合是特异性的，而不是非特异性的Fc受体或与其他蛋白的相互作用。还可以用来竞争性的结合抗体，与功能阻断抗体发挥同样的功能。 同型对照要与一抗的来源，Ig分型和标记完全一致。 如果一抗是多抗，可以用an normal serum（与一抗相同的正常血清） （must be the same species as primary antibody）。This control is easy to achieve and can be used routinely in immunohistochemical staining.这个可以咨询试剂商。同型对照为免疫荧光标记中的阴性对照。由于荧光标记单抗的组来源不同，应选用相同来源的未标记单抗作为同型对照来 调整背景染色。举个例子：比如检测一抗为单抗的mouse anti rat CD11b，clone OX-42 purified IgG，那么它的isotype 是mouse IgG2a， 所以可以用purified（纯化的） mouse IgG2a来做OX-42的同型对照（Isotype Control）。一般的的生物技术公司和国内的代理都有出售。 同型对照：是指与MoAb相同的、未免疫小鼠的免疫球蛋白亚类，若使用直接免疫荧光染色法，同型对照也应标记荧光色素，如IgG1 FITC、IgG2a、PE等。主要考虑了细胞的自发荧光、FC受体介导的抗体结合和非特异性抗体结合等影响因素。此外，同型对照与MoAb所标记的荧光 色素、浓度、F：P比值（标记的荧光色素与免疫球蛋白分子的比值）应该相同为最佳，这对准确设定阴性与阳性细胞的界标有重要意义，切忌使用与MoAb不相 匹配的同型对照，最好为同一实验室、采用相同工艺或方法制备（如同一品牌）的产品。
