Which Good's buffer for cell culture
Choose by pKa at the working temperature, not by the trade name.
Read: Which Good's buffer for cell culture →BSA: New Zealand, Australia, standard
Origin is not protease-free or IgG-free. Ask those separately.
Read: BSA: New Zealand, Australia, standard →Powder or sterile solution
Choose by storage, volume and assay needs, and state concentration and sterility on the inquiry.
Read: Powder or sterile solution →Sourcing or a reagent factory
One-stop inquiry, price comparison, customs clearance and batch COA/SDS.
Read: Sourcing or a reagent factory →Which IVD raw materials can be inquired
BSA, DTT, TMB, IPTG, buffer salts and Tween 20.
Read: Which IVD raw materials can be inquired →What to include
Names, CAS, salt, grade, pack, use and the files you need.
Read: What to include →Guanidine HCl or isothiocyanate
Unfolding uses the hydrochloride. Nucleic-acid release more often uses the isothiocyanate.
Read: Guanidine HCl or isothiocyanate →What to ask for Proteinase K
Activity, molecular-biology grade and nuclease-free are separate questions.
Read: What to ask for Proteinase K →Collagenase Type I, II and IV
The type is a supplier habit, not a strict tissue match.
Read: Collagenase Type I, II and IV →G418 sulfate for cell selection
Use the batch potency and a kill curve.
Read: G418 sulfate for cell selection →Why ELISA washes use Tween 20
PBST is often 0.05–0.1% Tween 20.
Read: Why ELISA washes use Tween 20 →Which DMSO grade for freezing cells
Cell-culture sterile, molecular-biology and industrial solvent grades are different inquiries.
Read: Which DMSO grade for freezing cells →For research or industrial use only. Not for human or animal diagnosis or treatment, and not for drug or food use. Grade, pack size and lead time follow the supplier batch COA / SDS. Figures on this site are general industry references, not a factory specification.
