Technical Data
Blimp-1 (BLIMP 1, BLIMP1, B Lymphocyte Induced Maturation Protein 1, Positive Regulatory Domain I Binding Factor 1, PR Domain Containing 1, PRDI BF1, PRDM1)
Blimp-1 (B lymphocyte maturation protein-1) is a nuclear protein with five zinc fingers in its carboxy terminus. It is a transcriptional repressor that is both required and sufficient to trigger terminal differentiation of B lymphocytes and monocyte/macrophages. Blimp-1 is expressed in, and may be required for terminally differentiated epithelial cells, retinal neurons and other lineage cells. It has also been implicated in the repression of beta-interferon (IFN-beta) and c-myc gene expression.

Suitable for use in Immunofluorescence, Flow Cytometry, ELISA, Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Immunofluorescence/Immunocytochemistry: 1:50-1:200
Flow Cytometry: 8ug/ml where cells are used at 2x10e6/ml
Western Blot: 1:1000
Immunohistochemistry (Paraffin): 1:200
Optimal dilutions to be determined by the researcher.

Positive Control:
P3X (murine plasmocytoma) cell lysates

Cellular Localization:

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20C. Aliquots are stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
