The Signal-Seeker™ line of produts have been developed to allow simple analysis of key regulatory protein modifications by specialists and non-specialists alike. The comprehensive Signal-Seeker™ kits provide an affinity bead system to isolate and enrich modified proteins from any given cell or tissue lysate. The enriched protein population is then analyzed by standard western blot procedures using a primary antibody to the target protein
Product Uses Include
- Investigate transient regulatory mechanisms
- Measure signalling events of multiple pathway member proteins
- Discover new modifications of your protein of interest
- Gain insight into regulatory mechanisms
- Measure endogenous or transiently expressed protein signalling events

Example results
There are many applications for these kits (see next section below), here we describe an interesting application for Rac1 protein:
Application 1: Investigate highly transient regulation events
Figure 1: Swiss 3T3 cells were pre-treated with MG-132, then either untreated or treated with CNF1 (CN04) for 3 hours prior to lysis with BlastR buffer. The BK161 kit was utilized to perform the IP on 300 μg of lysate per condition. Lane 1: 3 μg input untreated lysate, Lane 2: Ubiquitin Affinity beads (UBA01) plus untreated lysate, Lane 3: UBA01 plus CN04 treated lysate, Lane 4: ubiquitin control beads (CUB02) plus untreated lysate, Lane 5: CUB02 plus CN04 treated lysate. Samples were analyzed for Rac1 ubiquitination using an anti-Rac1 antibody.

用双氧水去除过氧化物酶时，我是自己配的3%双氧水滴到片上而非将片浸入双氧水，这样可否？
用博士德的DAB染色，配制方法为：1mlH20中加入DAB、H2O2、TBS各一滴，我配制的时候发现将DAB加入H20时很容易沉淀，要震荡才能混匀，且将配好的DAB滴到玻片上时，DAB会结为很小块的微颗粒悬浮在液体中但并不染色，是否DAB有问题？
现在打算换中衫的试剂盒，代理商说中衫的试剂盒包括了二抗和DAB，想请教一下该试剂盒的具体内容有些什么？
万分感谢！
上海好多的供应商的，具体还是看你选择了，其实试剂盒产品都差不多，什么远慕生物，古朵生物...好多的额
