Abstract: Herein is reported a method for producing an antibody comprising the steps of forming an antibody-antibody light chain affinity ligand complex, wherein the antibody light chain affinity ligand is immobilized on a solid phase, by applying a solution comprising the antibody to the immobilized antibody light chain affinity ligand, and incubating the complex formed in the previous step with one or more enzymes to modify the glycosylation of the antibody, thereby producing the antibody.

Abstract: A sanitary tubular pet waste removal device includes a hollow proximal section having a handle extending from a first end thereof and a hollow distal section extending from a second end of the proximal section, the second end opposite the first end. One or both of the distal and proximal sections includes a scoop arranged to nest within the sections when not in use, and the interior of the distal section is adapted to temporarily hold and sanitarily retain fecal matter. Together, the proximal and distal sections form a bat-like structure when not in use, thereby facilitating ease of carrying by a user. The handle of the proximal section includes a separable light source arranged to illuminate the exterior of the unit, acting as a safety light, and also arranged to shine down to the ground beneath, thereby facilitating the process of locating target fecal matter.
