Protocol

Cell experiment:

To study the effect of β-Casomorphin, human and DAMGO, cells are seeded in 12-well culture plates. Experiments are performed 3 (DHE cells) or 21 days (HT29-MTX cells) after confluency. Twenty-four hours before the studies, the culture medium is replaced by serum-free medium to starve the cells from serum and to eliminate any interference from extraneous proteins or hormones. The experimental protocol is then the following: the serum-free medium is removed, and the monolayer cultures of DHE or HT29-MTX are washed twice with PBS (37°C). Serum-free medium with or without β-Casomorphin, human or DAMGO is added to the cells and incubated at 37°C for 30 min to 24 h in a humidified atmosphere. μ-Opioid receptor blockade is performed by preincubating the cells with cyprodime for 30 min before agonist addition. The supernatants are then collected, frozen, and stored at 20°C. Cells are processed with trypsin. The cell numbers per well are determined, and total RNA is isolated. All experiments are performed at least three times in triplicate[2].

Background

β-Casomorphin, human is an opioid peptide, acts as an agonist of opioid receptor.

β-Casomorphin, human (TyrPro-Phe-Val-Glu-Pro-Ile) is also called human B-casein-(51-57), with the sequenceequivalent to bovine B-casein-(60-66) (Tyr-ProPhe-Pro-G]y-Pro-Ile or B-casomorphin-7)[1]. β-Casomorphin, human (100 μM) increases the expression of rat mucin (rMuc)2 and rMuc3 but not rMuc1, rMuc4, and rMuc5AC in rat DHE cells, also elevates increased MUC5AC mRNA levels[2].

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.
