The present invention concerns compositions and methods involving incubating biological materials under hypoxic or anoxic conditions to induce stasis or suspended animation. The removing member rubs against an extraneous-matter-adhered member, to which extraneous matter is adhered, so as to remove the extraneous matter therefrom. Then a tubing hanger is run through a drilling riser and landed in the wellhead housing. The one or more end caps may be designed to alter the shape of a package sleeve such as to increase the efficiency and ease of both the package assembly and product loading.
