Protocol

Laminin coating of culture plates:

For coating experiments, all laminin preparations were reconstituted in sterile PBS and then diluted to 10 μg/ml in PBS. Each laminin preparation was adsorbed to 6-well plates for 6 hrs at room temperature. Non-specific binding sites were blocked for 30 minutes with PBS containing 0.1% w/v BSA, at room temperature. Prior to seeding of cells onto the laminin-coated plates, the plates were washed with DMEM.

This protocol only provides a guideline, and should be modified according to your specific needs.

Background

Laminine (925-933) (CDPGYIGSR), est la séquence de Laminine sur la chaîne B1. YIGSR est actif dans la promotion de l'adhérence d'une variété de cellules épithéliales[1]. La laminine se lie au collagène IV, à la protéoglycane sulfate d'héparane et au nidogen-entactin, et elle médiatise les interactions cellulaires avec cette matrice[2].

Un peptide synthétique dérivé de la laminine, Cys-Asp-Pro-Gly-Tyr-Ile-Gly-Ser-Arg-NH2 (CDPGYIGSR-H2), contenant un site actif pour la liaison cellulaire a inhibé à la fois l'angiogenèse et la croissance des tumeurs solides[3].

In vitro, à des concentrations de 100 et 300 µg/ml, la laminine (925-933) peut stimuler l'attachement des cellules HT-1080 et CHO aux plaques de culture[2].

In vitro, le domaine oligopeptide Laminin (925-933) lié de manière covalente à un gel d'agarose en tant que substrat bioartificiel 3D supporte avec succès la croissance des neurites provenant des ganglions racines dorsales (DRG)[2]. In vitro, une réduction de 78% de l'attachement cellulaire a été observée sur les films contenant du Laminin (925-933) dans le milieu de culture cellulaire[4].

Des expériences in vivo ont révélé que le gel dérivé de la Laminine (925-933) avait la capacité d'améliorer la régénération nerveuse dans un modèle de racine dorsale de rat sectionnée par rapport à un gel non dérivé, un gel de Laminine (925-933) et des canaux de guidage nerveux remplis de solution saline[3].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
