The tissue culture polystyrene (TCPS) surface was coated with specifically composed biomimetic matrix according to the protocol of Prasad Chennazy and Krishnan.13 (link) One milliliter of the composed matrix comprised 5 mg in-house isolated human cryoprecipitate (clottable fibrinogen and fibronectin), 0.2% gelatin (Sigma), and 100 μg hyaluronic acid (in-house purified and characterized14 (link)), 20 μg of released platelet growth factor (PGF) prepared per Resmi et al.,15 (link) 25 μg laminin V (Sigma), and 250 ng recombinant epidermal growth factor (EGF; Sigma). Briefly, matrix composite was clotted on thrombin adsorbed TCPS to get a thin fibrin layer, and dishes were lyophilized under sterile atmosphere using a freeze drier (Edwards, Modulyo 4K). The TCPS immobilized with composite fibrin matrix were then stored at 4°C to 6°C until use.

Lapatinib was purchased from ChemieTek (Indianapolis, IN), afatinib (BIBW 2992) was from Selleckchem (Houston, TX), and canertinib (CI-1033, PD-183805) was kindly provided by Pfizer (Groton, CT), respectively. All kinase blockers were dissolved in DMSO and diluted 1:1,000 or 1:2,000 in medium before use. Recombinant epidermal growth factor (EGF) and heregulin-b1 (HRG-b1) were purchased from Sigma (St. Louis, MO). Fetal calf serum (FCS), DMEM, a-MEM, and RPMI 1640 were from GIBCO (Karlsruhe, Germany). The JNK inhibitor SP600125 and the STAT5 inhibitor II (IQDMA) were obtained from Selleckchem and from Merck (Darmstadt, Germany), respectively.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
