Extra Details:
Transition protein-1 is a spermatid-specific product of the haploid genome which replaces histone and is itself replaced in the mature sperm by the protamines. Yu et al. (2000) generated mice lacking the major transition nuclear protein, TP1, by targeted deletion of the Tnp1 gene in mouse embryonic stem cells. Surprisingly, testis weights and sperm production were normal in the mutant mice, and only subtle abnormalities were detected in sperm morphology. Electron microscopy showed large rod-like structures in the chromatin of mutant step 13 spermatids, in contrast to the fine chromatin fibrils observed in wildtype. Steps 12-13 spermatid nuclei from the testis of Tnp1-null mice contained, in place of TP1, elevated levels of TP2 (TNP2) and some PRM2 precursor. Applications: Suitable for use in Immunoprecipitation, Western Blot, Immunohistochemistry and Immunocytochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5-2ug/ml Immunohistochemistry: 5-20ug/ml Immunocytochemistry: 5-20ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
