Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form Lyophilized powder
Buffer before Lyophilization Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition Store at -20°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

1. We want to express this sequence, please send a quotation.
2. What is the endotoxin level when the customer receive protein?
3. To what extent do you usually remove endotoxin in in vivo experiments?
4. Can you offer stability test after protein expressinon ? If it is right, please let me know the price.

1. We could provide the endotoxin removal service for free. And you will receive the protein with entotoxin <1.0 EU/ug.
2. At present, we do not have a detailed stability test for individual proteins. From our current preservation situation, the liquid form protein (with 50% glycerol) could keep at -20℃/-80℃ for about 6 months.The lyophilized powder could be stored at -20°C/-80°C for about 12 months. If there is any instability occur during this period, we can provide complete after-sales services.
Q:

Could you please let me know the concentration ? Can I know it before ordering ?

A:
Thanks for your inquiry. Our normal concentration is 0.1-0.5mg/ml. If you have any request on the concentration, please communicate with us in advance.

Target Background

Function
(From Uniprot)
Involved in sperm-egg adhesion. Upon fertilization sperm must first penetrate a layer of cumulus cells that surrounds the egg before reaching the zona pellucida. The cumulus cells are embedded in a matrix containing hyaluronic acid which is formed prior to ovulation. This protein aids in penetrating the layer of cumulus cells by digesting hyaluronic acid.

  2. results indicate that neither rHuPH20 nor its directly generated HA catabolites have inflammatory properties in the air pouch model, and rHuPH20 can instead inhibit some aspects of inflammation, such as neutrophil infiltration into the air pouch. PMID: 24778442

  5. PH20 is elevated in demyelinating lesions and that increased PH20 expression is sufficient to inhibit oligodendrocyte precursor cell maturation and remyelination. PMID: 23463525
  6. SPAM1 mRNA & protein occur in all 3 regions of epididymis & vas deferens. It has hyaluronidase activity at pH 7.0. The proximal promoter has epididymal transcription factor sites including androgen receptor elements. Its role may be in sperm maturation. PMID: 12932297
