Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
What is the protein concentration of the solution of Product L2020, Laminin?
The protein specification for L2020 is 1.0 to 2.0 mg/mL. The exact value can be found on the lot-specific Certificate of Analysis, which can be downloaded from our website.
What type of laminin is Product L2020?
In the nomenclature system by Burgeson, this is Laminin 1. The laminins were numbered with Arabic numerals in the order discovered. The previous A, B1, and B2 chains, and their isoforms are listed by the Greek letters, for alpha, beta, and gamma, respectively, followed by an Arabic numeral to identify the isoforms. For example, the first laminin identified from the Engelbreth-Holm-Swarm tumor (EHS) was designated laminin-1 with the chain composition α-1/β-1/γ-1. The genes for these 3 chains are LAMA1, LAMB1, and LAMC1. Reference: Burgeson, R.E., et al., A new nomenclature for the laminins. Matrix Biol., 14, 209-211 (1994).
What is the purity of Laminin, Product L2020?
We do not determine a purity of this product. An SDS PAGE gel is run and the pattern (3 bands) is comparable to past lots.
Can I coat Laminin, Product L2020, on top of poly-L-lysine for better adherence?
When coating coverslips or slides for use with neural stem cells (neurospheres), the following procedure is recommended. Precoat the coverslips with poly-L-lysine (Product No. P5899) at 100 μg/mL. This is incubated for 30 minutes or more at room temperature. The coverslips are then washed with sterile water and allowed to dry. The poly-lysine coated coverslips can be stored at room temperature until ready to use (up to ~1 month). Coverslips are then coated with 30 - 50 μL of warmed laminin, which is at a concentration of 50 μg/mL. Incubate at 37°C for 30 minutes. Remove the laminin, and wash with DME (50 μL) twice. Cells are then added to the coverslips.
How can I store solutions of Laminin, Product L2020?
The product has a recommended storage temperature of -20°C. Please note, the product needs to be thawed slowly at 2-8°C. If the product has been warmed up at room temperature and it gels, it cannot be reactivated for use. We recommend storage at 2-8°C for up to one week. For longer storage, the product needs to be frozen at -20°C in single-use aliquots.
