Report
Bioactivity-ELISA
Immobilized Human CD47, Fc Tag (Cat. No. CD7-H5256) at 2 μg/mL (100 μL/well) can bind Human SIRP alpha, His Tag (Cat. No. SIA-H5225) with a linear range of 0.016-0.5 μg/mL (QC tested).
Protocol
Serial dilutions of Anti-Human CD47 Neutralizing Antibody were added into Human CD47, Fc Tag (Cat. No. CD7-H5256): Biotinylated Human SIRP alpha, Fc,Avitag (Cat. No. CDA-H82F2) binding reactions. The half maximal inhibitory concentration (IC50) is 0.5431 μg/mL (Routinely tested).
Protocol
Bioactivity-BLI
Immobilized Human CD47, Fc Tag (Cat. No. CD7-H5256) on AHC Biosensor, can bind Human SIRP alpha, His Tag (Cat. No. SIA-H5225) with an affinity constant of 0.72 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
Protocol
Bioactivity-FACS
FACS assay shows that Human CD47, Fc Tag (Cat. No. CD7-H5256) can bind to ACHN cell expressing SIRP-a. The concentration of CD47 used is 10 μg/mL (Routinely tested).
Protocol
FACS analysis shows that the binding of Human CD47 to ACHN expressing SIRP-a was inhibited by increasing concentration of neutralizing SIRP-a antibody. The concentration of Human CD47 used is 10 μg/mL. IC50=15.02 μg/mL (Routinely tested).

LikesHeard about ACRO from word of mouth from coworkers here at PPD and decided to browse the internet . My team purchased this product for some ELISA testing at the lab. We have been satisfied with the results so far. Great repeatability, sustainability, and specificity as compared to other vendors! It’s very creditable in my opinion. All and all ACRO definitely has some great quality products that are also more cost-effective compared to different vendors like MSD!- 1***02019-10-25 LikesI bought this product for ELISA test. The test has good repeatability. Compared to other products I purchased from other vendors, it has better specificity and is more cost-effective. It is a great choice.
