  • Background

    This permanent line is derived from a primary culture of late stage (L2) (20-24 hours old) Drosophila melanogaster embryos (Schneider, 1972) prepared in Scheiders insect medium. It is a positive control for the transcription factor GAGA ab11962.

Question

I have an other question : if I had to dilute this product, in wich buffer could I do this. Are the storage conditions different for the diluted aliquots. Thanks.

Answer

Thank you for your enquiry. The Drosophila SL2 lysate is supplied in 20% Glycerol, 20mM HEPES, 100mM Potassium Chloride, 1mM Magnesium Chloride, 0.5mM PMSF, 0.5mM DTT. pH 7.9. I would advise diluting the lysate in the same buffer and storing in aliquots at -20oC or -80oC. I hope this information helps. Please do not hesitate to contact me should you require further assistance.

Question

Hi, I have a couple of question about this product : - which is the quantity of droso cells necessary to obtain the 100 microgram lysate (approximately)? - what's the characteristic of these drosophila cells?, are they different from D.mel S2 (embryonic cells of Drosophila melanogaster)? Thanks

Answer

Thank you for your enquiry. May I please apologise for the delay to your question enquiring about the number of cells required to derive 100ug of lysate. The cell lysates were generated in large batches and then aliquoted, 100 ug per vial. Our supplier would estimate that it would take about 4 million SL2 cells to obtain 100ug of lysate. I hope this information helps. Please do not hesitate to contact me should you require further assistance.
