Dear colleagues, can you recommend some SDS PAGE gel-loading pipet tips (10-30 ug of protein sample) compatible with Eppendorf pipets (but not Eppendorf tips)?
we use for SDS-PAGE gel loading (samples with Laemmli, 5-30 µg) pipette tips from Bio-Rad (Prot/ElecTM, Catalog number: #2239915) and are very satisfied.
I load my samples with a 20 µL Hamilton syringe with a flat needle. For me, that works better than tips. I clean the syringe with tank buffer between samples, and with dd water afterwards.
