Tag Info
Tag type will be determined during the manufacturing process.
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
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°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.

Target Background

Function
Proton-conducting pore forming subunit of the membrane integral V0 complex of vacuolar ATPase. V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells. Required along with other vacuolar ATPase components for the removal of protein aggregates which form in immature oocytes in the distal gonad. This removal occurs as the oocytes mature and move to the proximal gonad, is triggered by the introduction of sperm through mating and occurs before fertilization. The introduction of sperm triggers V-ATPase accumulation in proximal oocytes and induces lysosomal acidification which leads to engulfing of protein aggregates by lysosomes and subsequent clearance of the aggregates. Lysosomal acidification also leads to changes in mitochondrial morphology and function. Mitochondria in distal immature oocytes are fragmented, produce high levels of reactive oxygen species (ROS) and have high membrane potential, indicative of metabolic inactivity. In contrast, mitochondria in proximal mature oocytes are tubular with lower ROS levels and membrane potential, indicative of an active metabolic state required for aggregate mobilization before clearance. Plays a role in the processing and secretion of the aspartic protease hrg-7 from the intestine.
