Indicative timelines: feasibility review and quotation in one to two business days; catalogue cells from stock in five to ten business days, two to three weeks if a specific donor profile has to be recalled and re-screened; custom assay development three to six weeks including your review of feasibility data; a full study with a formal report four to eight weeks from protocol sign-off. Cross-border shipping adds two to five days in transit plus customs. Dates are confirmed in writing with the quotation, and if a donor recall or a customs issue puts a date at risk you hear it the day we know, not at the deadline.
