应用
透明质酸酶是一种来自牛睾丸的酶。准备用于体外培养的卵子时，可利用这种酶去除小鼠胚胎分离物或新排卵中的卵丘物质。
促性腺激素用于使20只雌性小鼠超排卵。然后小鼠进行交配，获得并计数着床前期胚胎。然后胚胎使用透明质酸酶处理，知道其中所有积云物质都从胚胎里去除掉。胚胎被培育，每天查看，记录胚胎发育进展。

生化/生理作用
这些酶可随机裂解透明质酸、软骨素和硫酸软骨素中的 β-N-乙酰己糖胺-[1→4] 糖苷键。
透明质酸酶可降解透明质酸，并已发现可在癌症进展期间会被不适当地调节。
单位定义
在 37 ºC、pH 5.35 条件下，一单位每分钟可降解 0.75 μg 多糖透明质酸（通过比浊吸光度测量(λ: 600nm)，与 BSA 复合 45 分钟后测量）。
制备说明
用3 ml M2培养基（货号M 7167或M 5910）或去离子水复溶1瓶透明质酸酶，获得10 mg/ml的储备溶液。用M2培养基稀释储备溶液，至约300 μg/ml最终工作浓度。

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

Circular RNAs (circRNAs) have a critical role in the control of gene expression. Their function in spermatozoa (SPZ) is unknown to date. Twenty-eight genes, involved in SPZ/testicular and epididymal physiology, were given in circBase database to find which of them

A battery of chromatin modifying enzymes play essential roles in remodeling the epigenome in the zygote and cleavage stage embryos, when the maternal genome is the sole contributor. Here we identify an exemption. DOT1L methylates lysine 79 in the globular

Nanobodies present an appealing class of potential cancer therapeutics. The current study explores the in vivo expression of these molecules through DNA-encoded delivery. We hypothesized that this approach could address the rapid clearance of Nanobodies and, through half-life modulation, increase

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

实验方案
To measure hyaluronidase activity, a turbidimetric determination assay is used at 600 nm. One unit of hyaluronidase activity will cause a change in absorbance of 0.330 per minute at pH 5.35 at 37 °C.
在测定透明质酸酶活性时，使用了一种在600 nm处的比浊测定法进行测定。在pH 5.35、37 °C下，一单位的透明质酸酶活性可每分钟引起0.330的吸光值改变。
