UniProt Summary
FUNCTION: SwissProt: O43347 # RNA binding protein that regulates the expression of target mRNAs at the translation level. Regulates expression of the NOTCH1 antagonist NUMB. Binds RNA containing the sequence 5'- GUUAGUUAGUUAGUU-3' and other sequences containing the pattern 5'- [GA]U(1-3)AGU-3'. May play a role in the proliferation and maintenance of stem cells in the central nervous system (By similarity).

Entrez Gene Summary
This gene encodes a protein containing two conserved tandem RNA recognition motifs. Similar proteins in other species function as RNA-binding proteins and play central roles in posttranscriptional gene regulation. Expression of this gene has been correlated with the grade of the malignancy and proliferative activity in gliomas and melanomas. A pseudogene for this gene is located on chromosome 11q13.
Description:
Anti-Musashi-1
Background Information:
In mammals, the Musashi family is important for cell fate determination, playing roles in maintenance of the stem-cell state, differentiation and tumorigenesis. Musashi1 (also known as Msi1), is selectivley expressed in neural progenitor cells, including neural stem cells. Outside the nervous system, Musashi1 is a selective marker for intestinal stem or early lineage cells. Musashi1 interacts with the Notch pathway during asymmetric cell division by binding the 3' UTR of Numb. Numb is prevented from repressing Notch signaling when Musashi1 is present.
Alternate Names:
Musashi homolog 1; MSI1
Specificity:
Recognizes Musashi 1, a mammalian RNA binding protein that is preferentially expressed in neural progenitors capable of generating both neurons and glia during embryonic and postnatal development of the CNS. The molecular weight of the protein is approximately 39 kDa.
Key Applications:
- Western Blotting

Molecular Weight:
39 kDa
Control:
Mouse cortical neural stem cells (Catalog No. SCR029)
Presentation:
Affinity Purified immunoglobulin. Precipitated antibody in a solution of 50% saturated ammonium sulfate and PBS containing no preservatives.
Storage Conditions:
Maintain unopened vial at -70°C for up to 6 months. Avoid repeated freeze/thaw cycles.
PREPARATION AND USE:
To reconstitute the antibody, centrifuge the antibody vial at moderate speed (5,000 rpm) for 5 minutes to pellet the precipitated antibody product. Carefully remove the ammonium sulfate/PBS buffer solution and discard. It is not necessary to remove all of the ammonium sulfate/PBS solution: 10 µL of residual ammonium sulfate solution will not affect the resuspension of the antibody. Do not let the protein pellet dry, as severe loss of antibody reactivity can occur.
Resuspend the antibody pellet in a suitable biological buffer such as PBS or TBS (pH 7.3-7.5) to a final concentration of 1.0 mg/mL. For example, to achieve a 1.0 mg/mL concentration with 50 µg of precipitated antibody, the amount of buffer needed would be 50 µL.
Carefully add the liquid buffer to the pellet. DO NOT VORTEX. Mix by gentle stirring with a wide pipet tip or gentle finger-tapping. Let the precipitated antibody rehydrate for 1 hour at 4-25°C prior to use. Small particles of precipitated antibody that fail to resuspend are normal. Vials are overfilled to compensate for any losses.
The rehydrated antibody solutions can be stored undiluted at 2-8°C for 2 months without any significant loss of activity. Note, the solution is not sterile, thus care should be taken if product is stored at 2-8°C.
For storage at -20°C, the addition of an equal volume of glycerol can be used, however, it is recommended that ACS grade or higher glycerol be used, as significant loss of activity can occur if the glycerol used is not of high quality.
For long-term storage at -70°C, it is recommended that the rehydrated antibody solution be further diluted 1:1 with a 2% BSA (fraction V, highest-grade available) solution made with the rehydration buffer. The resulting 1% BSA/antibody solution can be aliquoted and stored frozen at -70°C for up to 6 months. Avoid repeated freeze/thaw cycles.
