| Description | Product Introduction:1. The Biotin Assay Blocking Kit is a kit primarily designed for blocking tissue and cell samples to significantly reduce background during detection processes such as immunohistochemistry (IHC), immunocytochemistry (ICC), immunofluorescence (IF), and fluorescence in situ Product Introduction:1. The Biotin Assay Blocking Kit is a kit primarily designed for blocking tissue and cell samples to significantly reduce background during detection processes such as immunohistochemistry (IHC), immunocytochemistry (ICC), immunofluorescence (IF), and fluorescence in situ hybridization (FISH). These detection methods are based on biotin and streptavidin or avidin, including the SABC (Streptavidin-Biotin Complex) method and ABC (Avidin-Biotin Complex) method.2. This kit contains two types of blocking buffers: Biotin Blocking Buffer (100X): Contains streptavidin and other components, which can fully bind to and block endogenous biotin, and reduce non-specific binding to labeled streptavidin in subsequent steps. Streptavidin/Biotin-Binding Blocking Buffer (100X): Contains biotin, which can fully block endogenous biotin-binding proteins and the streptavidin bound during the previous blocking step. Through this two-step blocking process, the goal of significantly reducing background can be achieved.3. This kit is suitable for blocking frozen sections and paraffin sections, and also applicable for blocking cultured cells.Product Features:1. Easy to Use – Can be performed simultaneously with the blocking step of conventional immunostaining, significantly saving blocking time.2. Stable Performance – Effectively reduces non-specific staining and improves detection sensitivity.Product Components and Storage Conditions:Product numberComponent200TStorageB1209118ABiotin Blocking Buffer (100×)200 µl-20ºCB1209118BStreptavidin/Biotin-Binding Blocking Buffer (100×)200 µl-20ºCOperating Steps:1. For immunostaining assays such as IHC, ICC, and IF:a. Dilution of blocking buffers: Based on the required volume, dilute Biotin Blocking Buffer and Streptavidin/Biotin-Binding Blocking Buffer to 1X using an appropriate conventional blocking buffer.b. After thorough washing of the sections and before primary antibody incubation, add an appropriate amount of Biotin Blocking Buffer and incubate for 10-30 minutes. Incubation for 10 minutes is recommended when diluted with a rapid immunostaining blocking buffer; incubation for 30 minutes is recommended when diluted with a regular blocking buffer.c. Wash the samples with washing buffer 3 times, 5 minutes each.d. Add an appropriate amount of Streptavidin/Biotin-Binding Blocking Buffer and incubate for 10-30 minutes. Incubation for 10 minutes is recommended when using a rapid immunostaining blocking buffer; incubation for 30 minutes is recommended when using a regular blocking buffer.e. Wash the samples with washing buffer 3 times, 5 minutes each.f. Proceed with subsequent steps such as primary antibody incubation according to conventional procedures.2. For in situ hybridization (FISH) detection:a. Dilution of blocking buffers: Based on the required volume, dilute Biotin Blocking Buffer and Streptavidin/Biotin-Binding Blocking Buffer to 1X using an appropriate diluent. The washing buffer for in situ hybridization can be used for dilution.b. Before hybridization with biotin-labeled probes, add an appropriate amount of Biotin Blocking Buffer and incubate for 15-30 minutes.c. Wash the samples with washing buffer 3 times, 5 minutes each.d. Add an appropriate amount of Streptavidin/Biotin-Binding Blocking Buffer and incubate for 15-30 minutes.e. Wash the samples with washing buffer 3 times, 5 minutes each.f. Proceed with subsequent steps such as hybridization with biotin-labeled probes according to conventional in situ hybridization detection procedures.Precautions:1. This kit can also perform the above-mentioned blocking steps after the primary antibody incubation is completed and the sample is washed 3-4 times with washing buffer, followed by subsequent steps such as secondary antibody incubation.2. This kit can simultaneously perform biotin-related blocking and conventional blocking, eliminating the need for additional conventional immunostaining blocking steps.3.

They can be used for the dilution of serum, plasma, blood, stool or urine samples, as well as the dilution of primary and secondary antibodies. Effect Diluents, Animal-free efficiently minimize matrix effects, cross-reactions and unspecific binding in immunoassays like ELISA, Western blotting, Immunohistochemistry, protein arrays and immuno-PCR.The Effect Diluents, Animal-free are used alternatively to the standard sample or antibody dilution buffers: In ELISA for the dilution of specimen and detection antibodies. In Western Blotting for the dilution of primary and secondary antibodies. In Protein arrays for the dilution of specimen and detection antibodies. In immuno-PCR as a washing buffer.Three versions of the diluent are offered: Low, Medium and High for optimal discrimination between specific and unspecific reaction and for minimizing strong interference effects e.g., by RF (rheumatoid factors), HAMAs (human-a-mouse Abs) or by endogenous components that bind and mask the analyte.Composition & Properties The Effect Diluents, Animal free contain no animal components and are free of phosphates.Working Procedure 1.Mix thoroughly prior to use. 2.Dilution recommendations a.Dilute antibodies according to the instruction of the antibody b.Dilution of the specimen is recommended at 1:2 or higherTips & TricksEffect Diluents must not be considered as blocking buffers. Recommended blocking buffers are: Synthetic Blocking Buffer, ELISA (cat. no. S494401), Synthetic Blocking Buffer, Blotting (cat. no. S494457) and WellChampion (cat. no. W494467) for plate blocking and stabilization (preparation of pre-coated plates). Complex sample matrices, such as serum and plasma, may contain interfering factors that affect the ability of the assay to accurately quantify the target analyte. Strong interferences are often caused by RFs and HAMAs. This matrix effect can cause high background in the negative control or false negatives in the sample measurement. To reduce this effect the samples can be diluted in the Effect Diluents, Animalfree.Handling & Storage Store solution 2-8°C or -15 to -30°C (tolerates freezing and thawing cycles)...

Polyunsaturated lipids are susceptible to an oxidative attack, typically by reactive oxygen species, resulting in a well-defined chain reaction with the production of end products such as malondialdehyde (MDA). Lipid peroxidation may contribute to the pathology of many diseases including atherosclerosis, diabetes, and Alzheimer′s.Lipid peroxidation (MDA) assay kit has been used to determine the levels of malondialdehyde (MDA).Suitability: Suitable for the measurement of malondialdehyde (MDA) in a variety of samples including tissue, cells and plasmaPrinciple: In this kit, lipid peroxidation is determined by the reaction of MDA with thiobarbituric acid (TBA) to form a colorimetric (532 nm)/fluorometric (λex= 532/λem= 553 nm) product, proportional to the MDA present...
