권장 분석 절차

Applications include gel shift, western blot analysis (1-2 µg/ml) and immunoprecipitation. The antibody has been shown to recognize in vitro translated PU.1 and PU.1 expressed as a recombinant protein in bacteria. In. In gel shift assays using µB as a probe (µB is a transcriptional element in the immunoglobulin heavy chain enhancer), G148-74 supershifts the complex of probe and PU.1.

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

G148-74

PU.1 is an ets-related transcription factor expressed in B lymphocytes and macrophages.  It was initially identified as the oncogene Spi-1 which was found to block erythroblast differentiation.  PU.1 functions by binding transcriptional control elements such as µB in the immunoglobulin heavy chain enhancer and π  adjacent to µE2.  It has been shown to form a complex with NF-EM5, a B cell transcription factor, resulting in the activation of the immunoglobulin κ 3'  enhancer.  PU.1 also appears to be critically involved in the control of monocyte development by regulating the expression of the macrophage colony-stimulating factor receptor.  PU.1 runs as a 40-42 kDa protein on SDS-PAGE. G148-74 recognizes human PU.1, an Ets-related transcription factor.  PU.1 is expressed in B lymphocytes and macrophages and like other Ets-related proteins, binds to consensus sites in DNA through an 85 amino acid Ets domain in the carboxyl terminal region of the protein. The antibody was raised against a bacterially expressed GST-PU.1 fusion protein.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
