Product Description
The Anti-Human IgM-coupled Magnetic Beads are 2.8 µm superparamagnetic particles covalently coupled to a highly affinity Monoclonal anti-human IgM antibody. The beads can be used to capture the Human IgM in Chemiluminescence procedures. It has no-corss-reactivity with Human IgG, IgA or IgE. The Anti-Human IgM-coupled Magnetic Beads is easy to capture the human IgM, and the bounded antibody have no activity lost, this ready to use products could greatly save your protein coupling time and hassle, and help us get the best performance and highly reproducible results.
Application
The Anti-Human IgM-coupled Magnetic Beads is used to capture the human IgM, it can combination with Acridinium ester markers in chemiluminescence technology, The Acridinium ester markers such as Streptavidin-Acridinium ester can capture the biotinylated proteins or molecules, this allows detection of antigen and antibody binding or antibody screening.
Reconstitution
See Certificate of Analysis (CoA) for detailed instruction.
Storage
Upon receipt, please store the Beads at -20℃. The shelf life is 1 year at -20 ℃.
Please avoid more than 3 freeze-thaw cycles once reconstitution, immediate use after reconstitution is highly recommended.

FAQ

Can lyophilized proteins remain stable during room-temperature shipping or temporary room-temperature exposure?
In general, lyophilized proteins remain stable during room-temperature shipping or temporary exposure to room-temperature conditions.
Many ACROBiosystems recombinant proteins are supplied in lyophilized (freeze-dried) form. The lyophilization process effectively removes moisture from the product, helping reduce degradation-related reactions and improve protein stability during transportation and storage.
To evaluate the stability of lyophilized proteins under normal temperature conditions, ACROBiosystems conducted a stability study on 11 representative lyophilized protein products at 37°C. The study demonstrated that these proteins maintained good quality stability after storage at 37°C for approximately 20 days. Based on these validation results, temporary room-temperature exposure during shipping or handling is generally not expected to have a significant impact on product quality or downstream application performance.
To ensure optimal long-term stability, products should be stored according to the storage conditions specified in the product Certificate of Analysis (COA) upon receipt.
