Fetal Spleen Lysate

Fetal human spleen tissue lysate was prepared by homogenization using a proprietary technique. The tissue was frozen in liquid nitrogen immediately after excision and then stored at -70˚ C. The fetal human spleen tissue total protein is provided in a buffer including HEPES (pH7.9), MgCl2, KCl, EDTA, Sucrose, Glycerol, Sodium deoxycholate, NP-40, and a cocktail of protease inhibitors. For quality control purposes, the spleen tissue pattern on SDS-PAGE gel is shown to be consistent for each lot by visualization with coomassie blue staining. The spleen tissue is then Western analyzed by either GAPDH or β -actin antibody, and the expression level is consistent with each lot.

Store at 2-8˚ C for continuous use. For extended storage, freeze working aliquots at -70˚ C. Repeated freezing and thawing is not recommended. Under proper storage conditions the shelf life is half a year from the date of receipt.
