Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
Musashi 1 also known as Msi1 is an RNA-binding protein with a mass of about 39 kDa. Msi1 is present in high levels in neural tissue and certain stem cells. It works mechanically by recognizing and binding to specific RNA sequences impacting the fate of the mRNA. Musashi 1 regulates the translation and stability of its target mRNA affecting protein synthesis at the post-transcriptional level. Its expression is not limited to neural tissues but is also detected in other tissues where stem or progenitor cells are present.
In neural stem cells and other tissue types Musashi 1 plays an important role in maintaining stem cell identity. Musashi 1 forms part of a complex that controls the translation of mRNAs involved in cell fate decisions. It acts by repressing or activating the translation of key regulatory proteins that guide stem cell maintenance and differentiation processes. This protein is also involved in cellular proliferation by influencing the translation of mRNAs tied to cell cycle regulation.
The function of Musashi 1 lies within critical signaling pathways such as Notch and Wnt. It facilitates these pathways by regulating the translation of downstream effectors which are necessary for cellular communication and differentiation. Musashi 1 associates with proteins like Numb a known Notch signaling inhibitor and β-catenin from the Wnt pathway modulating their effects on cell cycle progression and stem cell fate.
Musashi 1’s abnormal expression is often linked to conditions like glioblastoma and colorectal cancer. High levels of Musashi 1 can promote tumor growth due to its role in cell proliferation and differentiation pathways. In glioblastoma its expression relates closely with other oncogenic proteins such as Numb and Notch altering normal regulatory mechanisms. In colorectal cancer Musashi 1’s interaction with β-catenin further drives tumorigenesis highlighting its potential as a target for therapeutic interventions.
