Overview


Lee Biosolutions
sells research and bulk quantities of Recombinant Human Lysozyme, expressed in rice and purified from an animal free system.
.
Lysozyme lyses the peptidoglycan polymer typically found in most bacterial cell walls. Recombinant Lysozyme has identical amino acid sequences as the native Lysozyme. In lysing bacterial cells, recombinant Lysozyme is added to the cell extraction buffer at a range of 0.05 to 0.5 mg/mL (7,000 to 70,000 U/mL).
Typically, the extraction buffer contains 100mM tris HCL, 2mM EDTA, 0.05% trion I-100, pH 8.0. The cell paste is s

ended in extraction buffer and incubated for at least 15 minutes at room temperature. Alternatively, Triton X-100 at 1% and PMSF at 1mM can be added separately and the lysis solution is further incubated for at least 15 minutes at 37C. The lysed cell s

ension is clarified by centrifugation at 20,000 g for at least 15 minutes. The extraction conditions and concentration of recombinant lyosozyme needed for optiomal cell lysis and protein recovery depends on various factors.
Not only does lysozyme have very important clinical implications, but it is also a useful tool in molecular

ists. Cell lysis is necessary to extract recombinant proteins or DNA from bacterial cells. Human lysozyme is preferred to chicken lysozyme because it is up to four times more active. Also, the activity of chicken lysozyme has high lot-to-lot variation. Many recombinant protein production systems prefer an animal-free lysozyme to avoid the risk of infectious disease transmission.
