Target Information

Species

Drosophila melanogaster

Target Names

snf

Alternative Names

snf; D25; fs(1)1621; liz; CG4528; U1 small nuclear ribonucleoprotein A; U1 snRNP A; U1-A; U1A; Sex determination protein snf

Expression Region

1-216

Subcellular Location

Nucleus.

Protein Families

RRM U1 A/B'' family

Function

Binds stem loop II of U1 snRNA. It is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. Plays a role in regulating sex-lethal splicing.

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 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Lead Time

Delivery time may differ from different purchasing ways or locations, please kindly consult us for specific delivery times.

Storage & Handling

Storage Condition

Store at -20 °C/-80 °C upon receipt, aliquoting is necessary for multiple use.

Shelf Life

The shelf life is related to many factors, including 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.

Handling

Repeated freezing and thawing are not recommended.
