Format
Lyophilized
Reconstitution
Allow the vial and reconstitution buffer to equilibrate to room temperature. Briefly centrifuge or tap down the vial to ensure that all lyophilized powder is collected at the bottom of the vial. For the reconstitution of this product, we recommend adding PBS or sterile water to achieve a final antibody concentration of 1 mg/mL. Allow the vial to reconstitute for 10-15 minutes at room temperature with gentle agitation. Avoid vigorous shaking that can cause foaming and antibody denaturation. Aliquot into volumes based on your experiment and store liquid protein at -20°C or -80°C for long time.
Buffer
Lyophilized from sterile PBS
Preservative
None
Storage
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
More Infomation

Target

Full Name
tyrosinase (oculocutaneous albinism IA)
Function
This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the initial and rate limiting step in the cascade of reactions leading to melanin production from tyrosine (By similarity).
In addition to hydroxylating tyrosine to DOPA (3,4-dihydroxyphenylalanine), also catalyzes the oxidation of DOPA to DOPA-quinone, and possibly the oxidation of DHI (5,6-dihydroxyindole) to indole-5,6 quinone (PubMed:28661582).

Melanosome
Proper trafficking to melanosome is regulated by SGSM2, ANKRD27, RAB9A, RAB32 and RAB38.
Involvement in disease
Albinism, oculocutaneous, 1A (OCA1A):
An autosomal recessive disorder in which the biosynthesis of melanin pigment is absent in skin, hair, and eyes. It is characterized by complete lack of tyrosinase activity due to production of an inactive enzyme. Patients present with a life-long absence of melanin pigment after birth, and manifest increased sensitivity to ultraviolet radiation with predisposition to skin cancer. Visual anomalies include decreased acuity, nystagmus, strabismus and photophobia.
Albinism, oculocutaneous, 1B (OCA1B):
An autosomal recessive disorder in which the biosynthesis of melanin pigment is reduced in skin, hair, and eyes. It is characterized by partial lack of tyrosinase activity. Patients have white hair at birth that rapidly turns yellow or blond. They manifest the development of minimal-to-moderate amounts of cutaneous and ocular pigment. Some patients may have with white hair in the warmer areas (scalp and axilla) and progressively darker hair in the cooler areas (extremities). This variant phenotype is due to a loss of tyrosinase activity above 35-37 degrees C.
