If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Target Data

Gene References into Functions
  1. Unusual N-type glycosylation of salivary prolactin-inducible protein (PIP): multiple Lewis(Y) epitopes generate highly-fucosylated glycan structures. PMID: 29858715
  2. that GATA3 is a very sensitive marker for primary genital extramammary Paget diseases and is more sensitive than gross cystic disease fluid protein 15 PMID: 28693610
  3. monoclonal antibodies to GATA-3 are very sensitive reagents for the identification of breast CA, surpassing antibodies to GCDFP-15 and mammaglobin A, and offer a significant improvement in identifying TNBCs PMID: 26447897
  4. good coincidence was observed between primary and metastatic tumor GATA3 expression (kappa value = 0.826 >0.75) as compared with the coincidence of GCDFP15 (kappa value =0.492 <0.75) and mammaglobin (kappa value =0.593 <0.75) PMID: 28038704
  5. High expression of GCDFP-15 is associated with molecular apocrine breast cancer. PMID: 26711786
  6. While highly expressed under pathological conditions of the mammary gland, including breast cancers, PIP is expressed in very few other cancers. Although the function of PIP is not well elucidated, numerous studies suggest that its primary role may be related to host defense and immune modulation. Studies in Pip null mice suggest that PIP may play a similar immune-regulatory role in breast cancer. [Review] PMID: 27602994
  7. novel marker GATA3 stains a significantly higher proportion of both primary and metastatic breast carcinomas than GCDFP15 or mammaglobin with stronger and more diffuse staining, helpful in cases with small tissue samples PMID: 25906123
  8. In summary, this study suggests that PIP expression regulates the process of cell adhesion in breast cancer. PMID: 26585492
  9. GCDFP15 in stratum corneum is a potential marker for dysregulated sweating in atopic dermatitis. PMID: 25919462
  10. The commonly used breast carcinoma biomarkers vary in their prognostic implications. GCDFP-15 independently indicated a favourable prognosis. GATA-3 and MGB were not associated with outcome. PMID: 25425335
  11. Data indicate the potential role of Gross cystic disease fluid protein-15/prolactin-inducible protein (GCDFP-15/PIP) as a biomarker for keratoconus (KC)disease. PMID: 25405607
  12. Prolactin-induced protein mediates cell invasion and regulates integrin signaling in estrogen receptor-negative breast cancer. PMID: 22817771
  13. GCDFP-15 expression is higher in tumors with favorable prognostic features. GCDFP-15 expression is further a frequent feature of androgen receptor positive tumors and the molecular apocrine subtype. PMID: 25070172
  14. PIP is a breast cancer-related protein that is expressed in a majority of breast tumors and has a significant function in the biology of this disease. [review] PMID: 25472539

  16. The roles of PIP in the related T47D breast cancer cell line, were investigated. PMID: 23755096
  17. PIP is required for cell cycle progression in breast cancer and provides a rationale for exploring PIP inhibition as a therapeutic approach in breast cancer that can potentially target microtubule polymerization. PMID: 24862759

  23. GCDFP-15 alone is not a useful marker to detect the metastasis of basaloid type breast cancers. PMID: 23011826

  26. abnormal development of the prepuce in hypospadias is associated with variation in PIP expression PMID: 21883842
  27. Data suggest that Runx2 controls a positive feedback loop between androgen signaling and PIP, and pharmacological inhibition of PIP may be useful to treat PIP positive tumors. PMID: 21809344
