Overview
Rabbit myoglobin is a heme-containing protein primarily found in muscle tissues, where it facilitates oxygen storage and transport. It is structurally similar to hemoglobin but consists of a single polypeptide chain. Due to its stability and well-characterized properties, it is widely used in biochemical and biophysical research. In B2B contexts, rabbit myoglobin is often procured by laboratories, pharmaceutical companies, and diagnostic kit manufacturers. Its applications range from studying oxygen-binding mechanisms to serving as a standard in diagnostic assays. Buyers should prioritize suppliers who provide detailed purity and sourcing information.
Physical and Chemical Properties
Rabbit myoglobin has a molecular weight of approximately 17.8 kDa and exhibits a characteristic reddish-brown color due to its heme group. It is highly soluble in aqueous solutions, including buffers commonly used in laboratory settings. The protein's oxygen-binding capacity is pH-dependent, making it useful for studying physiological conditions. Its stability under various temperatures and pH levels makes it a reliable tool for research. However, prolonged exposure to extreme conditions can denature the protein, reducing its functionality. Proper storage at -20°C is essential to maintain its activity over time.
Main Applications
Rabbit myoglobin is primarily used in biochemical research to study oxygen transport and storage mechanisms. It serves as a model protein for understanding heme-protein interactions and folding dynamics. Additionally, it is employed in medical diagnostics, particularly in assays detecting muscle damage or cardiac events. In industrial settings, myoglobin derivatives are explored for their potential in artificial oxygen carriers and biosensors. Its compatibility with spectroscopic techniques like UV-Vis and NMR further expands its utility in structural biology studies.
Safety and Storage
While rabbit myoglobin is generally non-toxic, proper handling precautions are necessary to avoid contamination or degradation. Use gloves and lab coats when handling, and avoid inhaling powdered forms. Storage at -20°C in airtight containers is recommended to preserve its integrity. Repeated freeze-thaw cycles should be minimized, as they can lead to protein aggregation. For long-term storage, lyophilized forms are preferable, provided they are reconstituted under controlled conditions. Always check the manufacturer's guidelines for specific storage requirements.
B2B Procurement Guide
When procuring rabbit myoglobin, buyers should prioritize purity (typically >95%) and verify the source (recombinant or native). Reputable suppliers provide certificates of analysis (CoA) detailing endotoxin levels and biological activity. Bulk purchases may offer cost savings but require validation of batch-to-batch consistency. Prices vary based on purity and supplier, ranging from approximately $200 to $500 per mg. Consider lead times and shipping conditions, especially for international orders. Establish relationships with suppliers who specialize in research-grade proteins to ensure reliability and technical support.
