Is the product P4707 suitable for coating glassware for cell culture? Also, what is the difference between Poly L and Poly D lysine?
1 answer-
Yes, the product P4707 is suitable for coating glassware for cell culture. The difference between Poly L and Poly D lysine lies in their stereoisomeric properties. Poly-L-Lysine is a charge enhancer and can be used for coating many surfaces, including tissue culture plasticware and glassware. However, certain cells can digest poly-L-lysine, in which case the poly-D-lysine, such as P7405, should be used. This product can also be used to coat tissue culture plasticware and glassware.

How should I dilute Product P4707, Poly-L-Lysine solution?
1 answer-
For coating slides with poly-L-lysine, in general, it is recommended to use a 0.01% (w/v) solution. However, if your protocol requires a more dilute solution, you can add sterile water or sterile buffer like Phosphate Buffered Saline.

What is the protocol for using Product P4707, Poly-L-Lysine solution, to coat tissue culture plasticware?
1 answer-
A solution of 0.1 mg/mL is prepared; 0.5 mL of that solution is aseptically transferred to a non-tissue culture treated 25 square cm flask. The flask is gently rocked to evenly coat the surface. After five minutes, the excess solution is removed and the surface is thoroughly rinsed with sterile water and allowed to dry for several hours.

What molecular weight Poly-L-Lysine product should I choose?
1 answer-
The lower molecular weight poly-L-lysine (30-70 kDa) is easier to use because it is less viscous in solution, but the higher molecular weight poly-L-lysine (>300 kDa) provides more attachment sites per molecule. The mid-range product has a molecular weight range of 70-150 kDa.
