Description
Physiological Studies
-
Tick Feeding and Reproduction: CAPA neuropeptides, including PVK-2, are implicated in regulating feeding, survival, and reproduction in ticks. Silencing the CAPA receptor in Rhipicephalus microplus reduced female survival, egg mass weight, and hatching rates .
-
Fluid Homeostasis: PVK-2 homologs in insects and ticks influence Malpighian tubule function, suggesting a role in osmotic balance .
Receptor Studies
-
The CAPA/PVK receptor belongs to the PRX-amide GPCR family. Recombinant PVK-2 is used to study receptor-ligand interactions, particularly in tick synganglion and salivary glands .

Product Specs
Form
Lyophilized powder. We will ship the format in stock. If you have special format requirements, please note them when ordering.
Lead Time
Delivery time varies by purchase method and location. Consult local distributors for specifics. Proteins are shipped with blue ice packs. Request dry ice in advance (extra fees apply).
Notes
Avoid repeated freezing and thawing. Store working aliquots at 4°C for up to one week.
Reconstitution
Briefly centrifuge the vial before opening. Reconstitute in sterile deionized water to 0.1-1.0 mg/mL. Add 5-50% glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final glycerol concentration is 50%.
Shelf Life
Shelf life depends on storage conditions, buffer, temperature, and protein stability. Liquid form: 6 months at -20°C/-80°C. Lyophilized form: 12 months at -20°C/-80°C.
Storage Condition
Store at -20°C/-80°C upon receipt. Aliquot for multiple uses. Avoid repeated freeze-thaw cycles.
