Working concentrations for specific applications should be determined by the investigator. The appropriate concentrations may be affected by secondary antibody affinity, antigen concentration, the sensitivity of the method of detection, temperature, the length of the incubations, and other factors. The suitability of this antibody for applications other than those listed below has not been determined. The following concentration ranges are recommended starting points for this product. Western Blot: 1-2 µg/mLOther Applications: user optimized
Restrictions
For Research Use only
Format
Lyophilized
Buffer
PBS, pH 7.4, containing 0.02 % sodium azide
Preservative
Sodium azide
Precaution of Use
WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Storage
4 °C/-20 °C
Storage Comment
The antibody is stable in lyophilized form if stored at -20°C or below. The reconstituted antibody can be stored for 2-3 weeks at 2-8°C. For long term storage, aliquot and store at -20°C or below. Avoid repeated freezing and thawing cycles.
PU.1 known as Spi1 and Sfpi1, is an ETS-domain transcription factor essential for the development of myeloid and B-lymphoid cells. In myeloid cells, PU.1 may regulate transcription of both FMS and CD18/11B proteins that are central to the osteoclast phenotype. The failure to express PU.1 might preclude development of osteoclasts, leading to arrested bone resorption and osteopetrosis. PU.1 expression increases with the induction of osteoclastogenesis by either 1,25-dihydroxyvitamin D3 or dexamethasone which confirms the association between PU.1 and osteoclast differentiation. PU.1 Antibody, pAb, Rabbit is developed in rabbit using a KLH-coupled synthetic peptide from C-terminal of human PU.1 protein (Swiss Prot: P17947).
