GLP-1 drugs (exenatide, liraglutide etc), as well as GIP/GLP-1 hybrid peptides (tirzepatide), are clinically approved for diabetes and/or obesity, with GLP-2 based drugs (teduglutide) approved for the treatment of short bowel syndrome
Use of BPC-157 occurs outside approved regulatory frameworks, either as part of research protocols or through compounding pharmacies and research chemical suppliers
Rather than replicating the full TB4 protein, TB-500 is based on the short actin-binding fragment responsible for much of TB4s cell-migration activity, which makes it more practical to synthesise for research use
The day before the assay, frozen aliquots of the above-mentioned BHK cell lines were thawed, washed once in PBS (Gibco, #14190-094) and seeded in 40 L medium in a white 384-well culture plate (PerkinElmer, #6007688) at a cell density of 4000 cells/well and incubated in plastic bags over night at 37 C and 5% CO 2
Preventing Oxidation and Moisture Contamination Minimize Air Exposure: Limit the time peptide containers are open to reduce oxidation, especially for peptides containing cysteine (C), methionine (M), or tryptophan (W), which are prone to air oxidation
