Some peptides take longer to dissolve than others
The monophasic white coloured gel did not have desired gel like properties
Among the various diluents available, bacteriostatic water (BAC water) is commonly used in research laboratories because it contains a small amount of benzyl alcohol that helps inhibit bacterial growth after the vial has been opened

Calculated for precise dosing within research protocols: 1 ml = 100 units (IU) = 100 clicks 0.5 ml (one full rotation of the mechanism) = 50 clicks Examples of mixture dosing (BPC-157 + TB-500) for research purposes: 1 click = 0.10 mg (100 mcg mixture = 50 mcg BPC-157 + 50 mcg TB-500) 2 clicks = 0.20 mg (200 mcg mixture = 100 mcg BPC-157 + 100 mcg TB-500) 5 clicks (0.05 ml) = 0.50 mg (500 mcg mixture = 250 mcg BPC-157 + 250 mcg TB-500) 10 clicks (0.1 ml) = 1.00 mg (1000 mcg mixture = 500 mcg BPC-157 + 500 mcg TB-500) 20 clicks (0.2 ml) = 2.00 mg (2000 mcg mixture = 1000 mcg BPC-157 + 1000 mcg TB-500) This mechanical system guarantees absolute precision, repeatability, and flexibility when adjusting doses according to the requirements of a specific laboratory protocol without the need for complex manual mixing of two separate lyophilized vials

coli , where a specific pair of ribosomal proteins were deuterated (S2-S5, S5-S8, and S3-S7) not only provided information on the distances between the centers of gravity of three protein pairs, but also showed that S5 and S8 were compact and S2 was extended (Engelman et al., 1975)
