  • 产品描述：
    Recombinant Human Lactadherin (MFGE8) is a partial length protein expressed with an N-terminal 6xHis-SUMO-tagged in the E.coli. Its expression region corresponds to 24-387aa of human MFGE8 protein. Its purity was determined by SDS-PAGE and reached up to 90% and presented a molecular mass band of 56.8kDa on the gel. This recombinant MFGE8 protein may be used to synthesize antibodies against MFGE8 or on the studies of MFGE8-associated signal transduction. MFGE8 proteins in-stock are available.
    The MFGE8 gene encodes a preproprotein that is proteolytically processed to form multiple protein products. Among of these protein products, the major product, lactadherin, is a membrane glycoprotein that promotes phagocytosis of apoptotic cells. This protein has also been implicated in wound healing, autoimmune disease, and cancer. Additionally, lactadherin can be further processed to form a smaller cleavage product, medin, which comprises the major protein component of aortic medial amyloid (AMA). Diseases associated with MFGE8 include Anal Paget's Disease and Opisthorchiasis.

Product Type: In-stock Recombinant Protein
Stock Amount: Sufficient
Delivery Form: Liquid
Storage Buffer: 100 mM Tris-HCl, 0.4M Arg, pH 8.0, 50% glycerol
Endotoxin Level: <1.0 EU per 1μg of the protein by the LAL method (We will perform Endotoxin Removal upon your request.)
Q:

We are looking for sterile, no endotoxin Mfge8. Is this product available?

A:
Thanks for your inquiry.
If you request for Endotoxin Removal and Aseptic Processing, the lead time will be extended for 2-3 business days, so the total lead time will be 5-10 business days.
We could guarantee Endotoxin Level: <1.0 EU per 1μg of the protein by the LAL method.
We have tried several times to remove endotoxin from this protein but failed. If you want Endotoxin Removal and Aseptic Processing, we could try again, but the possibility of failure is great.
Would you please check what experiment you plan to perform? Could you accept if we finally fail to remove endotoxin from this protein?
Looking forward to your response. Have a nice day.
Q:

What is the endotoxin level of this lot? Do you product sterile MFGE8 (no endotoxin)?

A:
Thanks for your inquiry.
If you request for endotoxin removal and aseptic processing, the lead time will be extended for 2-3 business days.
We have tried several times to remove endotoxin from this protein but failed. If you want endotoxin removal and aseptic processing, we could try again, but the possibility of failure is great.
Would you please confirm what experiment you plan to perform. Could you accept if we finally fail to remove endotoxin from this protein?
Q:

Unfortunately, unless you can guarantee endotoxin removal we would not be able to accept the protein. We are looking for levels at zero but could accept <0.001 or in that region.

A:
Thanks for your response. As mentioned in the last email, we have tried several times to remove endotoxin from this protein but failed, so we can't guarantee. Sorry about this.
