| Introduction | |
| Cystatins are a superfamily of cysteine proteinase inhibitors found in both plants and animals. They comprise a group of proteinase inhibitors, widely distributed in tissues and body fluids, and form tight complexes with cysteine proteases such as cathepsin B, H, L and S. Cystatin C, a secreted molecule of this family, is of interest from biochemical, medicine and evolutionary points of view. Cystatin C, with molecular weight of 13260 Da, is composed of 120 amino acids, lacks carbohydrate and has two disulfide bridges located near the carboxyl terminus. Cystatin C is increased in patients with malignant diseases, and is related to the insufficiency of renal function and appears to be a better marker than creatinine. On the other hand, low levels of cystatin C involve cause the breakdown of the elastic laminae and, subsequently, the atherosclerosis and abdominal aortic aneurysm. | |

| HEK. | |
| Physical Appearance | |
| Sterile Filtered White lyophilized (freeze-dried) powder. | |
| Formulation | |
| The Cystatin-C was lyophilized from 1mg/ml in 1xPBS. | |
| Stability | |
| Lyophilized Cystatin-C although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Cystatin-C should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. | |
| Purity | |
| Greater than 95% as obsereved by SDS-PAGE. | |
| Biological Activity | |
| The inhibitory function of Cystatin-C on papin’s protease activity was measured by a colorimetric assay using L-BAPA as substrate. IC50 value was measured at 5-20 µg/ml (0.3-1.5 µM) with a range of 1.56-50 µg/ml Cystatin-C in presence of 0.55 µM papain and 0.44 µM L-BAPA. The activity is typically 0.3-1.5 µM IC50. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized Cystatin-C in sterile water not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | |
| Precautions | |

Background |
Retinol Binding Protein 4 (RBP4) is a multifunctional protein that plays a crucial role in the transport of retinol (vitamin A) in the bloodstream. Beyond its traditional role in vitamin A metabolism, RBP4 has emerged as a key player in various physiological processes and pathological conditions. This research endeavors to explore the diverse facets of RBP4 in human biology, shedding light on its physiological functions, regulatory mechanisms, and implications in health and disease. Physiological Functions: At its core, RBP4 acts as a carrier protein, shuttling retinol from the liver, where it is stored, to peripheral tissues where it is utilized. Retinol is vital for vision, immune function, growth, and development, making RBP4 an essential component in these processes. By regulating the availability of retinol, RBP4 contributes significantly to maintaining normal vision, immune responses, and cellular differentiation, particularly in epithelial tissues. Metabolic Significance: Research has unveiled RBP4’s role in metabolic regulation. It has been associated with insulin resistance, a hallmark of type 2 diabetes mellitus. Elevated RBP4 levels are observed in individuals with obesity and insulin resistance, implicating its involvement in metabolic disorders. Understanding the interplay between RBP4, insulin signaling, and glucose metabolism is crucial for deciphering the complexities of diabetes and metabolic syndrome. Immunological Implications: Beyond its metabolic functions, RBP4 has been implicated in immune responses. Studies have suggested its involvement in modulating inflammatory processes and immune cell functions. By influencing immune cell differentiation and cytokine production, RBP4 may play a role in both immune defense and autoimmune disorders. Investigating these immunological implications provides insights into the crosstalk between metabolic and immune pathways. Genetic and Environmental Influences: Genetic variations and environmental factors, such as diet and lifestyle, can impact RBP4 levels and functions. Research into these influences is essential for understanding individual susceptibility to metabolic disorders and inflammatory conditions. Genetic studies shed light on the hereditary aspects of RBP4 regulation, providing valuable information for personalized medicine approaches. Clinical Relevance: RBP4’s involvement in various diseases, including diabetes, cardiovascular diseases, and certain cancers, underscores its clinical relevance. It serves as a potential biomarker for metabolic dysregulation and a target for therapeutic interventions. Moreover, RBP4-targeted therapies are being explored for their potential in managing metabolic disorders and related complications. Conclusion: RBP4, once primarily recognized for its role in vitamin A transport, has evolved into a multifaceted protein with intricate roles in metabolism, immunity, and disease. Its functions extend far beyond being a mere carrier of retinol, influencing diverse physiological processes and serving as a nexus between metabolic health and immunological responses. Unraveling the complexities of RBP4 opens avenues for understanding diseases like diabetes and offers promising prospects for innovative therapies, emphasizing its significance in human biology and medicine. |
