A 30 gauge needle provides the best balance between injection comfort and adequate flow rate for the volumes involved
Peptides derived from cytoskeletal proteins also tended to increase in abundance with age, including proteoforms of dematin actin-binding protein (DMTN), paralemmin-1 (PALM) and microtubule-associated proteins 1/2 (MAP1/2), which may represent degradation of full-length cytoskeletal proteins in later life, leading to cytoskeletal instability 36
