应用

刚果红已可用于β淀粉样肽的染色。

生化/生理作用

刚果红是一种基于联苯胺的阴离子重氮染料。它是一种组织学染料,可与多种淀粉样蛋白结合,用于定量淀粉样蛋白β-肽聚集。刚果红还能与β-D-葡聚糖、含有连续β-(1→4)-键的D-吡喃葡萄糖基单元的多糖以及一些半纤维素半乳糖甘露聚糖发生相互作用。

适用性

经认证可用作明矾苏木精的复染剂,以及用于Puchtler淀粉样蛋白染色的Highman或Churukian修饰。

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. Why does the SDS for Congo Red list carcinogen as an OSHA hazard, (Section 2) but in Section 11 on carcinogenicity, it states that there is no component identified as a carcinogen?

    The reason that there is not an OSHA listing for carcinogens on most of SDS that have a hazard of a carcinogen hazard is because that section of the SDS is specifically for the OSHA regulated carcinogens, also referred to as the OSHA 13. Congo red at this time is not specifically called out  as a carcinogen by the other 3 Organizations listed (IARC, NTP, ACGIH) either. Congo red is listed by the European Classification Labeling & Packaging (CLP) Regulation (which is a pretty definitive guide for hazard classification), as a carcinogen. No other organizations have had the time to classify this material at this time. This is why it is only listed as a carcinogen in section 2 and in section 15.
