Additional Information: Sxl is the master regulator of sexual development and dosage compensation. M114 recognizes Sxl female isoforms (it may not recognize C-terminus variants) and will not recognize the two short male-specific isoforms. By western blot M114 recognizes two faint bands of 33 and 35 kDa only in head and thorax. Whole mount staining of embryos is specific for female embryos.
Recommended Applications: Chromatin Immunoprecipitation, Immunofluorescence, Immunohistochemistry, Immunoprecipitation, Western Blot

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable. For immediate use, short term storage at 4°C up to two weeks is recommended. For long term storage, divide the solution into volumes of no less than 20 ul for freezing at -20°C or -80°C. The small volume aliquot should provide sufficient reagent for short term use. Freeze-thaw cycles should be avoided. For concentrate or bioreactor products, an equal volume of glycerol, a cryoprotectant, may be added prior to freezing.
Usage Recommendations
Although the optimal Ig concentration for an application varies for each product and must be optimized for each laboratory, a good starting concentration for immunohistochemistry (IHC), immunofluorescence (IF), and immunocytochemistry (ICC) is 2-5 ug/ml. For western blots, the recommended concentration range is 0.2-0.5 ug/ml.
