Immunoelectrophoretic analysis of the porcine zona pellucida [PDF]
Reproduction, 1983 Summary. Antigens of the porcine zona pellucida were evaluated by 2-dimensional and line immunoelectrophoretic techniques. Zona antigen preparations studied included heat-solubilized isolated zonae pellucidae (SIZP), a purified 60 000 Mr glycoprotein (PPZA, purified pig zona antigen), and two fractions of this 60 000 Mr zona component

The influence of homogenous zona pellucida on human spermatozoa hyperactivation, acrosome reaction and zona binding [PDF]
, 2007 The study aimed to evaluate the changes in sperm motion characteristics and the occurrence of hyperactivation among sperm populations after exposure to human zona pellucida. Motile spermatozoa samples were used to evaluate the sperm-zona binding capacity,

Antigenicity of the Human Zona Pellucida [PDF]
Biology of Reproduction, 1977 Antigenicity of the human zona pellucida was investigated. Rabbit antiserum against saline homogenates of human ovary yielded a minimum of 9 precipitin bands when reacted against human ovary in agar-gel double diffusion analyses. The same antiserum also cross-reacted in varying degrees when tested against 21 other human tissues and fluids. Anti-human-

Structural analysis of peptide-analogues of human Zona Pellucida ZP1 protein with amyloidogenic properties: insights into mammalian Zona Pellucida formation. [PDF]
PLoS ONE, 2013 Zona pellucida (ZP) is an extracellular matrix surrounding and protecting mammalian and fish oocytes, which is responsible for sperm binding. Mammalian ZP consists of three to four glycoproteins, called ZP1, ZP2, ZP3, ZP4.

MIS12 Is Required for Kinetochore‐Microtubule Attachment in Oocyte Meiosis
Advanced Science, EarlyView.A model depicting the role of MIS12 in K‐MT attachment during oocyte meiosis. The presence of MIS12 stabilizes bipolar K‐MT attachments by maintaining the function of NDC80 and its interaction with TUBB. This, in turn, promotes KNL1 assembly and subsequent SAC protein recruitment to kinetochores.

From Cytoskeletal Remodeling to Oocyte Quality: The Emerging Role of Mechanics
Advanced Science, EarlyView.Mechanical properties of the oocyte are increasingly recognized as critical determinants of meiotic success and developmental potential. How actomyosin remodeling controls oocyte mechanics, how these properties are altered in pathological conditions, and how they could serve as markers in reproductive medicine are examined.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope
Animal Research and One Health, EarlyView.FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable
