背景（Background）
Bovine serum, primarily composed of Bovine Serum Albumin (BSA), is widely used in biological product manufacturing. However, as a heterologous protein, BSA poses risks such as immunopathological reactions, allergies, and immunogenicity, potentially compromising product safety and efficacy.
To address this, global regulatory authorities enforce strict quality control measures. These include optimizing production processes, validating purification methods, and employing sensitive analytical techniques to minimize BSA residues to acceptable levels. Such controls are essential to ensure the safety, efficacy, and regulatory compliance of biological products.
应用说明（Application）

Detection of BSA (Bovine Serum Albumin) by ELISA Assay.
Immobilized Anti-BSA Antibody can bind BSA (Bovine Serum Albumin) Detection was performed using HRP-Anti- BSA Antibody with sensitivity of 0.5 ng/mL (QC tested). For each experiment, a standard curve needs to be set for each micro-plate, and the specific OD value may vary depending on different laboratories, testers, or equipments. The following example data is for reference only.
验证（Validation）
稀释线性（Dilution Linearity）
To assess the linearity of the assay, samples spiked with high concentrations of BSA were serially diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.
批内差异（Intra-Assay Statistics）
Three samples of known concentration were tested ten times on one plate to assess intra-assay precision , Intra-Assay Precision CV≤15%.
批间差异（Inter-Assay Statistics）
Three samples of known concentration were tested in three separate assays to assess inter-assay precision, Inter-Assay Precision CV≤15%.
准确度（Accuracy）
Five samples of known concentration were tested ten times to assess Accuracy , Accuracy recovery rate 80-120%.
干扰效应(Interference effect)
Verify potential matrix effects by adding different levels of specific buffers to the sample buffer. For specific buffers, it is recommended that you verify recovery to determine the optimal dilution ratio.
专属性（Specificity）
High, medium and low concentrations of BSA were added to Human serum (v/v 1%), Mouse serum (v/v 2.5%), Human Serum Albumin (1.25mg/mL) and Rabbit serum (v/v 10%), the recovery rate of BSA was used as the specific validation index.
High, medium and low concentrations of BSA were added to MDCK Cell, HEK293 Cell, CHO Cell , T Cell and VERO Cell, the recovery rate of BSA was used as the specific validation index.
