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）
The kit is developed for the detection and quantitative determination of BSA. It is used as a tool to aid in optimal purification process development and in routine quality control of in-process streams as well as final product by various biotechnological processes such as cell or tissue culture .The standard BSA has been calibrated against NIFDC standard (cat # 140619) for accurate assay result.
It is for research use only.
存储（Storage）
1. Unopened kit should be stored at 2℃-8℃ upon receiving.
2. Find the expiration date on the outside packaging and do not use reagents past their expiration date.
3. The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.

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）
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 ten 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)
We have conducted interference effect test about frequently-used buffers, they have excellent buffer compatibility. For specific buffers, it is recommended that you verify recovery to determine the minimum dilution ratio.
专属性（Specificity）
High, medium and low concentrations of BSA were added to Human serum (v/v 1%), Horse serum (v/v 10%) , Human Serum Albumin (1.25 mg/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( 2×106 cells/mL), HEK293( 3.5×106 cells/mL) , CHO( 2×106 cells/mL) and T-lymphocyte( 2.15×106 cells/mL) the recovery rate of BSA was used as the specific validation index.
