Estas enzimas rompen aleatoriamente los enlaces glucosídicos β-N-acetilhexosamina [1→4] del ácido hialurónico, la condroitina y los sulfatos de condroitina.
La hialuronidasa degrada el hialuronano y se ha observado que su regulación no es apropiada durante la progresión del cáncer.
Application
Hyaluronidase is an enzyme derived from bovine testes. It is used to remove the cumulus mass in the isolation of mouse embryos or from newly ovulated eggs, when preparing the eggs for in vitro culture.
Gonadotropins are used to superovulate 20 female mice. The mice are then mated and preimplantation stage embryos are retrieved and counted. The embryos are treated with hyaluronidase until the cumulus mass is dissociated from the embryos. The embryos are cultured, viewed daily and progress of the embryos is recorded.

Other Notes
One unit will degrade 0.75 μg of the polysaccharide hyaluronic acid per minute at pH 5.35 at 37 ºC (as measured by turbidimetric absorbance (λ: 600nm) when complexed with BSA after 45 minutes).
Preparation Note
Reconstitute 1 vial of hyaluronidase with 3 ml of M2 Medium (Product Nos. M 7167 or M 5910) or deionized water to obtain a 10 mg/ml stock solution. Dilute stock solution with M2 Medium to obtain a final working concentration of approximately 300 μg/ml.

Checkpoint-inhibiting antibodies elicit impressive clinical responses, but still face several issues. The current study evaluated whether DNA-based delivery can broaden the application of checkpoint inhibitors, specifically by pursuing cost-efficient in vivo production, facilitating combination therapies, and exploring administration routes that lower

Bone formation in mammals requires continuous production of osteoblasts throughout life. A common molecular marker for all osteogenic mesenchymal progenitors has not been identified. Here, by lineage-tracing experiments in fetal or postnatal mice, we discover that Gli1

Mammalian histone methyltransferase G9a (also called EHMT2) deposits H3K9me2 on chromatin and is essential for postimplantation development. However, its role in oogenesis and preimplantation development remains poorly understood. We show that H3K9me2-enriched chromatin domains in mouse oocytes are generally depleted

HIV-associated neurocognitive disorders (HAND) continue to persist despite effective control of viral replication. Although the mechanisms underlying HAND are poorly understood, recent attention has focused on altered neuronal population activity as a correlate of impaired cognition. However, while alterations in
