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.

General description
La poli-L-lisina es una polímero de aminoácido con carga positiva con aproximadamente un HBr por residuo de lisina. El hidrobromuro permite a la poli-L-lisina estar en una forma cristalina hidrosoluble. Puede encontrarse una pequeña cantidad del producto en la estructura beta porque el HBr interfiere en el enlace de hidrógeno entre el grupo amino y los grupos carboxilo o los grupos que contienen N u O.
Application
Los polímeros de poli-L-lisina pueden utilizarse en la promoción de la adhesión celular a los sustratos sólidos, la conjugación al metotrexato para incrementar el transporte de medicamentos, la microencapsulación de islote, la tecnología de microencapsulación celular, recubrimiento de portaobjetos de vidrio de micromatrices y preparaciones cromosómicas. La poli-L-lisina de menor peso molecular (30 000-70 000) es menos viscosa en disolución, pero las versiones de mayor peso molecular proporcionan mas sitios de unión por molécula.
- Se han utilizado cubreobjetos de vidrio recubiertos con poli-L-lisina para montar muestras para el microscopio electrónico de barrido.
- Se utilizaron pocillos recubiertos con poli-L-lisina para atrapar células PC-12 en los electrodos.
- Se utilizaron portaobjetos de vidrio borosilicato recubiertos con poli-L-lisina para la siembra de células transducidas con vectores víricos.
Biochem/physiol Actions
La poli-L-lisina es un factor de unión inespecífica a las células útil en la promoción de la adhesión celular a los sustratos sólidos intensificando la interacción electrostática entre iones con carga negativa de la membrana celular y la superficie del cultivo. Cuando se absorbe a la superficie del cultivo celular, la poli-L-lisina funciona aumentando el número de sitios con carga positiva disponibles para la unión a la célula. Con las células que pueden digerir la poli-L-lisina, debe utilizarse la poli-D-lisina como factor de fijación.
Preparation Note
Este producto se suministra como una disolución al 0,01% en agua esterilizada por filtración. El recubrimiento de los portaobjetos con esta disolución debe ir seguido de una incubación de 5 minutos y de secar los portaobjetos a temperatura ambiente. Los portaobjetos recubiertos serán estables durante un año si se protegen del polvo.

Should I use Poly-L-Lysine or Poly-D-Lysine?
1 answer-
Certain cells secrete proteases, which can digest poly-L-lysine. For those cell types, poly-D-lysine should be used.

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.

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.
