Poly-D-lysine coating coverslips for cell culture

​

Neuvitro Corporation owns the leading technology to provide professional coating with the broadest coverage of substrates, such as PDL, PLL, PLO, Collagen, Gelatin, Laminin, Fibronectin, PDL+Laminin, PDL + Fibronectin, PLO+Laminin, PLO+Fibronectin, PDL+Laminin+Fibronectin, etc. The majority of coated German coverslips available from Electron Microscopy Science, ThermoFisher Scientific, and VWR is actually manufactured by Neuvitro Corporation. Free samples are available.

Poly-D-Lysine promotes the adhesion of cultured cell onto coverslips. The polycationic property of the molecule allows interaction with anionic sites on the cells promoting effective attachment to the growing surface.

  3. Add enough coating solution to cover culture surface completely and incubate for 5 minutes at room temperature.

  4. Remove coating solution and rinse 2 times with PBS or serum- free culture medium.

  5. Use immediately or let it dry for future use.

 

Sigma-Aldrich

  1. Add 50ml of sterile water to 5mg of poly lysine.

  2. Coat cell culture surface with 1ml per 25cm² culture surface

  3. Incubate 5 minutes.

  4. Remove poly lysine solution and rinse the plate thoroughly with sterile water and let it dry at least 2 hours

Poly D lysine coating protocol from protocols online

Poly-D-lysine solutions are typically used to coat glassware and plasticware  for the attachment and growth of cells.

Preparation

  1. Prepare a stock solution by dissolving 100 mg polylysine in 100 ml water (poly-L-lysine or poly-D-lysine can be used; check specific protocol for choice of isomer)and filter sterilize through a 0.22-micron  filter.

  2. Store in 5-ml aliquots at -20°C.

Coating culture dishes, multiwell plates, or chamber slides

  1. When ready to use, dilute 1 part stock solution with 19 parts water to prepare a 50 ?g/ml working solution.

  2. Fill tissue culture dishes, multiwell plates, or slide wells with the working solution and incubate 1 hr in a 37°C incubator, then remove solution by vacuum aspiration and allow surface to dry.

  3. To coat coverslips: Sterilize coverslips by autoclaving or by incubating them in 95% ethanol and drying before coating. Place coverslips in a single layer in a petri dish containing working solution and incubate 1 hr at 37°C. Remove coverslips using sterile forceps and allow surface to dry.

  4. Store coated tissue culture ware up to 3 months at 4°C. Use diluted solutions only once.

  5. When coating with poly-D-lysine, the efficiency of coating is relatively low when prepared with distilled water due to the acidic pH of the solution that can range between a pH of 3.3-6.6. One recommendation [1] to improve coating is to use an 8.5  pH borate buffer to dissolve the lysine, with thorough rinsing after coating. In addition to the basic techniques shown here, there are a variety of approaches recommended by vendors as shown below.
